Top contact organic thin-film field effect transistors based on regioregular poly(3-butylthiophene-2,5-diyl) (P3BT), poly(3-dodecylthiophene-2,5-diyl) (P3DDT) and poly(3-hexylthiophene-2,5-diyl) (P3HT) of similar concentration were fabricated by spin coating technique. The current-voltage (I-V) characteristics of these three different polymer based organic field-effect transistors (OFETs) were studied...
An organic thin film transistor (OTFT) based on chemically synthesized poly-3-hexylthiophene (P3HT) is successfully fabricated and I–V characteristics of the device is measured at room temperature. The key performance parameters such as ON/OFF ratio, threshold voltage, carrier mobility, conductivity and transconductance are extracted through the I–V characteristics of OTFT and discussed in the paper.
In heart rate variability studies PWLL the p-Wave Locked Loop, is used to determine instantaneously the p-p time interval of the ECG. The reported version of the PWLL needs the user to operate a manual switch as to changeover from the r-r pickup to p-p determination and locking. In order to make this changeover an automatic issue this paper proposes a modification to the PWLL such that no additional...
