Transparent p‐type CuI layers with high hole mobility can be fabricated on flexible plastic sheets, a system which has been unattainable with p‐type transparent oxide semiconductors. Mildly heat‐treated CuI layers have mobilities of ≈20 cm2 V−1 s−1, which are comparable to those of p‐type GaN epilayers. Highly transparent p–n diodes with sufficient rectification ratio (106) can be manufactured by employing a heterojunction of p‐type CuI and amorphous n‐type In‐Ga‐Zn‐O layers on plastic sheets. Thus, CuI can be regarded as an excellent transparent p‐type semiconductor for flexible transparent electronics.

在柔性塑料板上制造的高迁移率透明p型CuI半导体层:面向柔性透明电子

具有高空穴迁移率的透明p型CuI层可以在柔性塑料板上制造,这是p型透明氧化物半导体无法实现的。经过轻度热处理的CuI层的迁移率约为20 cm 2 V -1 s -1,与p型GaN外延层的迁移率相当。可以通过在塑料板上使用p型CuI和非晶n型In-Ga-Zn-O层的异质结来制造具有足够整流比(10 6)的高度透明的p-n二极管。因此,CuI被认为是用于柔性透明电子产品的优秀透明p型半导体。
