Antimony Trisulfide Heterojunction Vidicon Structures

摘要: Publisher Summary This chapter examines the various aspects of antimony trisulfide heterojunction vidicon structure. Antimony has been extensively used as photoconductive material in vidicons, and it also structures a nonphotosensitive element. The presence emission limited contacts to Sb 2 S 3 , requirements useful target are established. It is demonstrated that properly designed junction can reduce dark current arising from electron injection without affecting other characteristics. use structure ensure absence ohmic or quasiohmic relaxes inherent restriction imposed on resistivity . electrical contact characteristics were found. was found such reduction permits operation at higher applied fields, which turn, yield sensitivity approaching quantum unity for peak response wavelength.
