Abstract(in English) | AlGaN surface barrier heights in AlGaN/GaN heterostructure field-effect transistors (HFETs) with and without SiN passivation were estimated in detail by x-ray photoelectron spectroscopy (XPS) and capacitance-voltage (C-V) measurements. SiN passivation was performed by catalytic chemical vapor deposition (Cat-CVD), which has been already found to increase two-dimensional electron gas (2DEG) density. In this contribution, we demonstrate that a reduction of AlGaN surface barrier height is actually induced by Cat-CVD SiN passivation, which is most likely to be a significant factor of increase in the 2DEG density of AlGaN/GaN HFETs. |
