Ohmic contacts are crucial for both device applications and the study of fundamental physics. From the perspective of device scaling trends, nano-scale Ohmic contacts are indispensable for future LSI technologies such as metallic source and drain contacts. In this study, we investigate the I-V characteristics using a varying discrete level distribution based on our previously-proposed model. Our calculated results show that linear I-V properties can be obtained from uniform discrete level distributions.
