Shunt current in InAs diffused photodiodes
The shunt current has been investigated in ⁺- type InAs diffused photodiodes. The mesastructures were prepared by etching in Br₂-HBr solution and sequentially etched in CP-4 and in a lactic acid-based etchant. The surface of mesastructures was passivated in an alcohol solution of Na₂S. After each ch...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The shunt current has been investigated in ⁺- type InAs diffused photodiodes. The mesastructures were prepared by etching in Br₂-HBr solution and sequentially etched in CP-4 and in a lactic acid-based etchant. The surface of mesastructures was passivated in an alcohol solution of Na₂S. After each chemical treatment, the current-voltage and capacitance-voltage characteristics were measured as functions of bias voltage and temperature. It has been shown that the shunt current contains ohmic and non-ohmic components. Evidence has been obtained that the non-ohmic shunt current originates from the space-charge limited current in the surface inversion layer and the trap-assisted tunneling current in the bulk.
