The transfer of the carrier in photoconductor is anisotropy owing to the column structure of the film is anisotropy . on the basis of the new concept suggested in this paper , the maximum diffusion length in the lateral direction of the photo - carrier in the photoconductor ( which is related to the resolution of lclv directly ) as function of conductivities of both in lateral and normal directions in the film can be obtained as the expression as following . the nc - si / a - si : h photoconductor of lclv deposited and crystallized at low temperature of exactly 250 c stack column structure by al inducing a - si : h 本文根據柱狀結構存在各向異性的特點,并根據半導體物理知識,推出光導層光生載流子橫向最大擴散長度(該擴散長度與液晶光閥光導層分辨率直接相關)與薄膜橫向和縱向電導率關系的表達式為:由于a - si : h在al金屬的誘導作用下在不高于250的溫度下即開始晶化,本文對用金屬al誘導非晶硅晶化制備的nc - si a - si : h薄膜進行研究。
