Noble metal schottky contacts on nanocrystalline RF sputtered ZnO thin film. Rajan, L., Periasamy, C, & Sahula, V. In 2017 Conference on Emerging Devices and Smart Systems (ICEDSS), pages 63-67, March, 2017.
doi  abstract   bibtex   
Schottky contacts on ZnO thin film have been synthesized using noble metals like Pt, Pd and Au on n-Si substrate using radio frequency sputtering technique. Electrical characterizations of all the three Schottky diodes have been conducted using semiconductor parameter analyzer. Important empiric parameters of the fabricated Schottky diodes such as barrier height, saturation current, ideality factor and series resistance have evaluated at room temperature and compared. Cheung's method has been used along with thermionic emission model to calculate series resistance of the devices. The results have confirmed that the Schottky contacts formed on ZnO thin film are suitable for potential electronic device applications. TCAD simulation using SILVACO ATLAS package has also been done and the Schottky diode parameters are obtained.
