Abstract
This paper explores possibility of device as well as circuit performance enhancement in the bottom gate ZnO based TFT via Mg and Cd material doping. DC, Analog & RF performance, Energy efficiency and Noise analysis were performed for both doped (i.e., MgyZn1-yO and CdxZn1-xO) and undoped ZnO channel TFT structures. Further, successful circuit implementation of these devices was done in resistive inverter and AMLCD pixel display circuits. Performance wise both MgyZn1-yO and CdxZn1-xO channel TFTs were found to be superior against its undoped variant. ~ 376%, ~ 105% and ~ 162% are the percentage improvement in (ION/IOFF) ratio, field effect mobility (μFE) and effective mobility (μeff) for CdxZn1-xO based TFT with respect to ZnO based TFT, same parameters show ~ 194%, ~ 103% and ~ 133% percentage improvement for the case of MgyZn1-yO TFT. Also, ~ 23% is percentage decrease in subthreshold swing (SS) for CdxZn1-xO based TFT with respect to ZnO based, whereas ~ 11% is percentage decrement for MgyZn1-yO. Intrinsic gate delay, the percentage decrement is ~ 54.15 and ~ 59.95% for MgyZn1-yO and CdxZn1-xO respectively w.r.t ZnO. Both the CdxZn1-xO and MgyZn1-yO TFT shows unanimous decrease in delay for the resistive inverter as well as AMLCD pixel display circuits. The reported results shows that bottom gate CdxZn1-xO TFT has better performance for above-mentioned performance parameters. The numerical simulations are performed on Silvaco ATLAS TCAD simulator.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).
