Fabrication and DC characterization of InAs/AlSb self-switching diodes

Paper i proceeding, 2012

Fabrication and DC measurements of an InAs/AlSb self-switching diode (SSD), aimed for THz detection, is presented. An SSD with a channel width of 160 nm and a trench width of 240 nm was designed and fabricated in a process using an in situ passivation procedure of the oxidation-sensitive trench. Rectifying behavior was observed in the I-V characteristics. The device performance was relatively stable over a period of three months.
