An Organic Temperature Sensor Based on Asymmetric Metal Insulator Semiconductor Capacitor With Electrically Tunable Sensing Area

An area-asymmetric organic metal-insulator-semiconductor (AMIS) capacitor is described, which exhibits strong temperature dependence. The gate electrode in the device is made much larger than the top electrode so that a significant fraction of the capacitance comes from the channel. This contribution, being dependent on mobility, has a strong temperature dependence, giving rise to a capacitor with positive temperature coefficient. The advantage of the proposed device as a temperature sensor includes not only the simplicity of fabrication but the ability to electrically tune the effective sensing area using voltage and frequency as well. Experimental results obtained with poly-4-vinyl-phenol/pentacene-based AMIS capacitor show that temperature coefficient as large as 1.98 10 2C1 can be obtained at a gate voltage of 15 V and a measurement frequency of 1 kHz.
