摘要: To improve the electroluminescence (EL) intensity of the hydrogenated amorphous silicon carbide (a-SiC:H) p-i-n thin-film light-emitting diode (TFLED), a barrier-layer (BL) structure had been inserted at its p-i interface and used to enhance the hole injection efficiency of TFLED under forward-bias operation. Two TFLEDs with different BL structures were studied. The device I had a 25 Angstrom A i-type single-barrier structure and the device II had an i-type double-barrier structure of barrier (10 Angstrom A)/well(10 Angstrom A)/barrier(10 Angstrom A). The obtainable brightness of device I was 342 cd/m(2) at an injection current density of 600 mA/cm(2). On the other hand, the device II had a brightness of 256 cd/ m(2) at 800 mA/cm(2). These brightnesses were about 3 orders of magnitude higher than that of a basic a-SiC:H p-i-n TFLED.
