Study of Degradation Processes Kinetics in Ohmic Contacts of Resonant Tunneling Diodes Based on Nanoscale AlAs/GaAs Heterostructures under Influence of Temperature.

The artificial aging of resonant tunneling diodes based on nanoscale AlAs/GaAs heterostructures was conducted. As a result of the thermal influence resonant tunneling diodes IV curves degrade firstly due to ohmic contacts' degradation. To assess AlAs/GaAs resonant tunneling diodes degradation level and to predict their reliability, a functional dependence of the contact resistance of resonant tunneling diode AuGeNi ohmic contacts on time and temperature was offered.
