However, the poor thin film quality and surface roughness of ZnO have hindered its use in TFTs. Recently, novel structures have been proposed to improve the performance of ZnO TFTs.Objectives:The main objectives of this study are to:1. Develop a model for ZnO TFTs to investigate the impact of interface states, surface roughness, and trap density on device performance.2. Fabricate and characterize novel ZnO TFT structures, such as those incorporating nanocrystals or nanowires, to determine their potential advantages over traditional ZnO TFTs.3. Investigate the use of different gate dielectric materials to improve the electrical characteristics of ZnO TFTs.Methods:The modeling of ZnO TFTs will be carried out using device simulation software, while the novel structures will be fabricated using various deposition techniques, including physical vapor deposition and chemical vapor deposition. The electrical properties of the TFTs will be characterized using various methods, including current-voltage measurements and capacitance-voltage measurements.Expected Outcomes:The expected outcomes of this study are as follows:1. A better understanding of the critical factors affecting the performance of ZnO TFTs, including interface states, surface roughness, and trap density.精品文档---下载后可任意编辑2.
