Electroluminescence with high and stable quantum efficiency and low threshold voltage from anodically oxidized thin porous silicon diode

Abstract: Highly efficient electroluminescence (EL) is obtained at low operating voltage (<5 V) from n+-type silicon-electrochemically oxidized thin porous silicon–indium–tin–oxide junctions. Continuous wave external quantum efficiency greater than 1% and power efficiency of 0.37% have been achieved. Considerable reduction of leakage current accounts for the enhancement of EL efficiency upon oxidation. The EL time response (≈30 μs) is slower than the photoluminescence one, due to slow electrical charging of porou… Show more

“…The low matrix defect density has allowed us to obtain a power efficiency of 1.2ϫ 10 −3 % for the best result, corresponding to an external quantum efficiency of 0.03%. In general, authors only report external quantum efficiency, which is the upper limit for power efficiency, 25 but power efficiency values are the one required for application purposes. To our knowledge, the value of power efficiency we report is the highest reported in Si-ncl sensitized Er ion systems.…”

“…This work has been focused on the building blocks of photonic communication systems such as lasers [5][6][7][8], modulators, photodetectors, and others [9][10][11][12][13][14][15]. Our work has been focused on developing a hybrid integration platform that allows for III-V material functionality, such as light amplification and detection, to be utilized on silicon waveguide based devices.…”

“…During that time silicon technology has significantly improved and correspondently the quantum efficiency of silicon LEDs was raised from 10 6 to several percents [2][3][4]. One of the milestones on this way was the evidence of visible light emission from avalanche porous silicon (PS) reverse biased diodes [5].…”
