A gas-sensitive field effect transistor utilizing a thin film of lead phthalocyanine as the gate material

Electrical properties and dielectric relaxation of thermally evaporated zinc phthalocyanine thin films

“…In the past three decades, phthalocyanine (Pc) compounds have attracted much attention because they have enormous potential for applications, such as semi conducting devices [1,2], photovoltaic and solar cell [3,4], gas sensors [5,6], and optical recording [7]. Pcs are interesting groups of compounds because their structure corresponds to porphyrine of which chlorophyll is a member and they have chemical and photochemical stability [8,9].…”

Alternating current measurements of thermally evaporated triclinic lead phthalocyanine thin films

“…In recent years, many researchers focussed their attention on technological applications of these compounds especially in fields of photovoltaic (PV) cells [1], light emitting diodes (OLED) [2], field effect transistors (FETs) [3] and finally gas sensors [4]. DC electrical measurements play an important role in characterization of device parameters and have extensively been studied [5,6].…”

Chemical Gas Sensors Based on Organic Semiconductor Polypyrrole

“…[43][44][45][46][47][48] For the devices chemical-sensitive organic layers can been used either as gate [49][50][51] or as bulk material. 52,53 With both types good results have been achieved for the detection of reducing and oxidizing gases.…”
