Cut in voltage of silicon

WebAny diode drops a particular amount of voltage across its terminals. A diode voltage drop of 0.7 V means the voltage through the resistor or load present in the circuit is (supply voltage – 0.7) volt. The voltage drop across different diodes are different. Typically it ranges from 0.6 to 0.7 volts for a small silicon diode. WebDec 1, 2024 · We report on the fabrication of a low-cut-in voltage (a-SiC:H/Si) heterojunction diode using femtosecond laser ablation of silicon wafers in an octane environment. The femtosecond laser-induced plasma simultaneously reduces, carburizes, and hydrogenates the p-type silicon to develop a layer of hydrogenated silicon carbide …
