Thermally Stimulated Current Measurement in Highly Elongated Polyethylene Film

초고연신 고밀도 폴리에틸렌의 열자극전류

The trap depth and its density of highly elongated polyethylene have been studied by thermally stimulated current measurements. Three discrete traps with depth of 0.13 0.3 and 0.5 eV have been evaiuated using the initial rise method in the temperature region 77 to 390 K ; these change slightly with the elongation ratio. A trap density of the order of $10^{13}-10^{14}/cm^3$ has been calculated from the area of TSC peaks.
