wo dimensional (2D) van der Waals (vdW) nanosheet semiconductors have recently attracted much attention from researchers because of their potentials as active device materials toward future nano-electronics and -optoelectronics. This review mainly focuses on the features and applications of state-of-the-art vdW 2D material devices which use transition metal dichalcogenides, graphene, hexagonal boron nitride (h-BN), and black phosphorous: field effect transistors (FETs), complementary metal oxide semiconductor (CMOS) inverters, Schottky diode, and PN diode. In a closing remark, important remaining issues of 2D vdW devices are also introduced as requests for future electronics and photonics applications.

In this report, high-resolution metal electrode patterning is demonstrated by using selective surface treatment and dip casting for low-cost printed electronic applications. On hydrophobic octadecyltrichlorosilane treated $SiO_2$ surface, deep UV irradiation was performed through a patterned quartz photomask to selectively control the surface energy of the $SiO_2$ layer. The deep UV irradiated region becomes hydrophilic and by dipping into Ag nano-ink, Ag patterns were formed on the surface. Using this patterning technique, line patterns and dot arrays having less than $10{\mu}m$ pitch were fabricated.

It is strongly expected that inkjet printing method will be play and important role on printable electronics such as 3D integration of embedded ceramic devices(capacitor, resistor, inductor and electrode or circuit), Si-TFT and organic TFT including display C/F, RFID, FPCB, and etc. A inkjet printing method had been center of attention to strengthen the competitiveness of flat panel display on market and to open the new world of manufacturing process of printable electronics. We will survey the industrial tendency of printable electronics and flat panel display including some examples of inkjet printing and present the considerable points of inkjet printing method and some role of materials for successful inkjet printing.

We report on carbon nano-fibers (CNFs) for applying to epoxy as a highly thermal conductive adhesive. In order to fabricate CNFs, electro-spinning process was performed with polyacrylonitrile (PAN) solutions. The sample was stabilized at the annealing temperature of $360^{\circ}C$, and carbonized from 900 to $1100^{\circ}C$. It is shown that the synthesized CNFs have a good thermal conductivity of several hundred W/m K. LED backlight units (BLUs) fabricated with MPCB using CNF-mixed epoxy give a better heat dissipation and higher performance than normal LED BLUs. On the basis of SEM, XRD, and FTIR, the characteristics of CNFs are described.

We proposed new triode-type Field Emitter Arays using Carbon NanoTubes(CNT-FEAs) as electron emission sources at low electric fields. The CNTs were selectively grown on the patterned catalyst layer by Plasma-Enhanced Chemical Vapor Deposition (PECVD). In this structure, gate electrodes are located underneath the cathode electrodes and extracted gate is surrounded by CNT emitters. Furthermore, in order to control density of CNTs, we investigated effect of using rapid thermal annealing (RTA).

In this paper, we proposed the store monitoring system using smart hanger. This system consists of smart hanger, server, and wireless communication module. The smart hanger consists of LCD, MCU, RF module. In order to verify the effectiveness of the proposed smart hanger, we performed the experiment. This smart hanger can be used for shopping mall to increase sales.
