WebOct 29, 1999 · Alternative semiconducting materials for thin-film field-effect transistors (TFTs), which have mobilities at least comparable to that of amorphous silicon (a-Si) and may also be easily processed with low-cost techniques, are required to enable new opportunities for display and storage technologies. WebNov 10, 2024 · We explore the reasons for this mobility gap by conducting contact resistance (RC) and interface trap (D it ) analysis. We find that the mobility difference can be minimized by reducing the high contact resistance (~33% of the total resistance in the ON-state) and high density of interface traps (~3 × 10 13 cm -2 eV -1 ).
