F. Giorgis, OPTICAL AND PHOTOLUMINESCENCE PROPERTIES OF A-SI1-XNX-H A-SI3N4-H ANDA-SI1-XCX-H/A-SIC-H SUPERLATTICES/, Philosophical magazine. B. Physics of condensed matter. Statistical mechanics, electronic, optical and magnetic, 76(3), 1997, pp. 287-298
Superlattices based on wide-bandgap hydrogenated amorphous silicon bas
ed alloys were studied in terms of optical absorption and photolumines
cence properties. A critical comparison between a-Si1-xNx:H/a-Si3N4:H
and a-Si1-xCx:H/a-SiC:H multilayers was made, revealing the former as
a promising structure for electroluminescent devices in the visible ra
nge. As evidence of this potentiality, a light-emitting device was rea
lized using an a-Si1-xNx:H/a-Si3N4:H multilayer as the radiative eleme
nt.
