| dc.description | This work presents the electrical and
electroluminescent properties of light emitting capacitors (LECs)
using silicon rich oxide (SRO) and the effect of a thin silicon rich
nitride (SRN) film on it (SRN/SRO) as active layers. LECs were
fabricated using simple Metal–Insulator–Semiconductor (MIS)
structures with indium tin oxide (ITO) and aluminum as gate
and substrate electrodes, respectively. All devices exhibit a
resistance switching (RS) behavior from a high conduction state
(HCS) to a low conduction state (LCS), enhancing an intense
ultraviolet-blue (UV-B) EL. This RS behavior produces
structural changes in the active layer and probably in the ITO
contact. Seven narrow bands with half-peak width of 7±0.6 nm at
~250, 270, 285, 305, 325, 415 and 450 nm are clearly observed
once the low conduction state is reached. The red-near infrared
EL at HCS is similar to the PL spectra indicating the same
radiative process is involved. An increment of the EL band at
~590 nm in SRN/SRO is observed at both conduction states. This
band has been observed before and attributed transitions from
the minimum band conduction to K0 centers in SRN films. The
UV-B emission appears at lower electric field when the SRN/SRO
film is used as active layer. | |
