  • We review our studies on the growth of microcrystalline silicon films by the standard PECVD technique. In situ spectroscopic ellipsometry studies allow the optimization of the complex film structure with respect to competing aspects of the growth process. Fine tuning the hydrogen flux, the ion energy, and the nature of the species contributing to deposition produces unique films with a fully crystallized interface with silicon nitride. These materials have been successfully incorporated in bottom gate TFTs which present mobility values in the range of 1 to 3 $cm^2/V.s$, and stable characteristics when submitted to a bias stress. The stability of these TFTs makes them suitable for driver applications in AMLCDs as well as pixel elements in OLED displays.

  • Due to the development of the media, the digital image is gradually developed, giving some motion to the still image called Cinemagraphs, thereby enhancing the visual perceptional ventilation. In today's advertising media, visual stimuli are transmitted through Cinemagraphs. Demonstrate what is conveyed by aesthetics through case studies and experimental studies. In addition, through Cinemagraphs, the possibility of aesthetic technique is confirmed, and the features of Cinemagraphs will become a new trend in the field of design studying digital images. As IT technology becomes increasingly sophisticated and easy to make, it is expressed as a cultural symbolic pleasure of the masses. The value of future research will be significant.

  • Ever since they were first produced, more than four hundred years ago, Shakespeare's plays have been reproduced and adapted into countless film and TV productions, into ballets and operas and theatre performances across the globe. The present paper, within a broad conceptual framework, aims to investigate the cross cultural dimension of adaptation of a stage play, written for the Renaissance England, into a $21^{st}$centuryIndianfeaturefilm. The paper uses Omkara, an adaptation of Othello by Vishal Bharadwaj, as a case study to: (i.) Explore the use of the idiomatic language of cinema in such an adaptation. (ii.) Posit a re-reading of Shakespeare with the help of local/native signifiers.

  • Oxide semiconductors such as zinc tin oxide (ZTO) or indium gallium zinc oxide (IGZO) have attracted a lot of research interest owing to their high potential for application as thin film transistors (TFTs) [1,2]. However, the instability of oxide TFTs remains as an obstacle to overcome for practical applications to electronic devices. Several studies have reported that the electrical characteristics of ZnO-based transistors are very sensitive to oxygen, hydrogen, and water [3,4,5]. To improve the reliability issue for the amorphous InGaZnO (a-IGZO) thin-film transistor, back channel passivation layer is essential for the long term bias stability. In this study, we investigated the instability of amorphous indium-gallium-zinc-oxide (IGZO) thin film transistors (TFTs) by the back channel contaminations. The effect of back channel contaminations (humidity or oxygen) on oxide transistor is of importance because it might affect the transistor performance. To remove this environmental condition, we performed vacuum seasoning before the deposition of hybrid passivation layer and acquired improved stability. It was found that vacuum seasoning can remove the back channel contamination if a-IGZO film. Therefore, to achieve highly stable oxide TFTs we suggest that adsorbed chemical gas molecules have to be eliminated from the back-channel prior to forming the passivation layers.

  • Liquid-assisted cleaning technology utilizing a nanosecond laser pulse is effective for removing submicron particulates from a variety of solid substrates. In the technique, saturated vapor is condensed on a solid surface to form a thin liquid film and the film is evaporated explosively by laser heating. The present work studies the role of liquid-film evaporation in the cleaning process. First, optical interferometry is employed for in-situ monitoring the displacement of the laser-irradiated sample in the cleaning process. The experiments are performed for estimating the recoil force exerted on the target with and without liquid deposition. Secondly, time-resolved visualization and optical reflectance probing are also conducted for monitoring the phase-change kinetics and plume dynamics in vaporization of thin liquid layers. Discussions are made on the effect of liquid-film thickness and dynamics of plume and acoustic wave. The results confirm that cleaning force is generated when the bubble nuclei initially grow in the strongly superheated liquid.

  • In this paper, a high-performance optical gating in a junction device based on a vanadium dioxide dioxide ($VO_2$) thin film grown by a sol-gel method was experimentally demonstrated by directly illuminating the $VO_2$ film of the device with an infrared light at ~1554.6 nm. The threshold voltage of the fabricated device could be tuned by ~76.8 % at an illumination power of ~39.8 mW resulting in a tuning efficiency of ~1.930 %/mW, which was ~4.9 times as large as that obtained in the previous device fabricated using the $VO_2$ thin film deposited by a pulsed laser deposition method. The rising and falling times of the optical gating operation were measured as ~50 ms and ~200 ms, respectively, which were ~20 times as rapid as those obtained in the previous device.

  • This paper presents a magnetostrictive transpositioner and its fabrication process. To get a transposition movement without shifting or twisting, it is designed as an array type. To fabricate the suggested design, micromachining and selective DC magnetron sputtering processes are combined. TbDyFe film is sputter-deposited on the back side of the bulk micromachined transpositioner, with the condition as: Ar gas pressure below $1.2{\times}10^{-9}$ torr, DC input power of 180W and heating temperature of up to $250^{\circ}C$ for the wireless control of each array component. After the sputter process, magnetization and magnetostriction of each sample are measured. X-ray diffraction studies are also carried out to determine the film structure and thickness of the sputtered film. For the operation, each component of the actuator has same length and out-of-plane motion. Each component is actuated by externally applied magnetic fields up to 0.5T and motion of the device made upward movement. As a result, deflections of the device due to the movement for the external magnetic fields are observed.

  • In the history of cinema, Sergei Eisenstein is always considered as a pioneer to conceive of cinema primarily as a form of expressing thought rather than as a representation of reality. For him, montage is the indispensable method to construct an open totality of thought and image in movement. It functions as a basic thread running through two poles of filmic composition, that is, the organic and the pathetic. The organic is concerned with the composition of the film structure as a whole, while the pathetic is involved in an ongoing process of registering a leaping point in various filmic sequences. The ultimate goal of montage for Eisenstein is to create the cinema of ideas which can synthesize both emotional and intellectual elements in the filmic composition. In his system of intellectual cinema, the identity of image and thought externalizes the sensory-motor unity of nature and man along the ascending spiral of centrifugal force of the film. Indeed, in both theory and practice, Eisenstein firmly argues that nature not only provides basic laws for the organic composition of the film, but also expresses itself in the form of the whole which brings out the experience of totality in the film text, the audience, and surely Eisenstein himself.
