论文摘要
二维(2D)和三维(3D)材料的异质结构形成了有效的设备,用于利用两类材料的性质。石墨烯/硅(g/si)Schottky二极管已经相对于其光电特性进行了广泛的研究。在这里,我们介绍了一种分析与G/Si Schottky二极管的测得的电容 - 电压数据,该数据与G/硅二氧化硅/SI(GIS)电容器并联。我们还证明了内置电势($φ$$ _ {bi} $)的准确提取和从与Richardson Constant无关的测量数据中的Schottky屏障高度。
Heterostructures of two-dimensional (2D) and three-dimensional (3D) materials form efficient devices for utilizing the properties of both classes of materials. Graphene/silicon (G/Si) Schottky diodes have been studied extensively with respect to their optoelectronic properties. Here, we introduce a method to analyze measured capacitance-voltage data of G/Si Schottky diodes connected in parallel with G/silicon dioxide/Si (GIS) capacitors. We also demonstrate the accurate extraction of the built-in potential ($Φ$$_{bi}$) and the Schottky barrier height from the measurement data independent of the Richardson constant.
