TL;DR: In this paper, Ni Schottky contacts on AlGaN/GaN heterostructures have been fabricated, and the samples are then thermally treated in a furnace with N2 ambient at 600 °C for different times (0.5, 4.4, 5, 10.1, 18, 33, 48 and 72 h).
Journal ArticleDOI
Influence of thermal stress on the relative permittivity of the AlGaN barrier layer in an AlGaN/GaN heterostructure Schottky contacts

TL;DR: In this paper, the relative permittivity of the AlGaN barrier layer was found to be related to the piezoelectric and spontaneous polarization of the barrier layer, and the conclusion can be made that a moderate thermal stress can restrain the converse PDE effect and can improve the stability of AlgaN/GaN heterostructure devices.
