During this year, the progress mainly including 3 parts:1. Clarify the electron tunneling behavior in MIM diodes with electric field concentration effect. Establish a comprehensive model for electron tunneling that considers the configuration and effect of the MIM diode.2. Design and fabricate MIM diodes with nanoparticles (NPs) to achieve electric field concentration effect. Optimize the configuration of the MIM diode using finite element method and fabricate a platinum NPs array using atomic layer deposition.3. Characterize the MIM diode with NPs, and demonstrate a significant improvement of ~300 times in rectification performance comparing with the MIM diode without NPs.

于本年度内，本集团之进展主要包括三部分：1.阐明了MIM二极管在电场集中效应下的电子隧穿行为。建立了一个综合考虑MIM二极管结构和效应的电子隧穿模型.设计并制作具有奈米粒子的MIM二极体，以达到电场集中效应。利用有限元法优化MIM二极管的结构，并利用原子层沉积法制备了铂纳米颗粒阵列.表征具有NPs的MIM二极管，并证明与不具有NPs的MIM二极管相比，整流性能显著提高约300倍。
