WebDec 1, 2001 · 1. Introduction. In 2 Se 3 is a semiconductor that exhibits a number of structural modifications. Four phases have been detected: α, β (rhombohedral), γ and δ (the last two are hexagonal) [1]. The α-phase can be either rhombohedral or hexagonal [1]. For the hexagonal type, the space group P6 3 /mmc was assigned [1], [2], [3], [4]. WebApr 10, 2024 · The use of unipolar barrier structures that can selectively block dark current but allow photocurrent to flow unimpededly has emerged as an effective strategy for constructing high-performance photodetectors.
