Abstract
In this letter, we study the current-temperature-stress-induced electrical instability of single and multiple hexagonal (HEX) hydrogenated amorphous silicon (a-Si:H) thin-film transistors (TFTs) connected in parallel. The influence of the threshold voltage shift of a single HEX TFT on the overall electrical performance of multiple HEX TFTs is discussed. The results indicate that a-Si:H HEX TFTs have an improved electrical stability and a threshold voltage shift linear dependence on a number of connected HEX-TFT units.
