Py. Du et al., NEAR IR SENSITIVE LIQUID-CRYSTAL LIGHT VALVE WITH HYDROGENATED AMORPHOUS-SILICON PHOTOCONDUCTOR, I.E.E.E. transactions on electron devices, 43(2), 1996, pp. 360-362
ITO/a-Si:H photosensor has been used in near IR sensitive LCLV. Tn pre
paration of the photosensor, two main problems have been solved. One i
s the enhancement of IR transmittance of ITO; the other is improvement
of the ratio of photo/dark conductivity in a-Si:H at near IR range, A
s the results, IR transmittance as high as 80% and ratio of photo/dark
conductivity larger than one order of magnitude are obtained. The ima
ges converted from near IR scenery by the LCLV are observed.
