Electrical and Optical Properties of Heavily Ge-Doped AlGaN
R. Blasco, A. Ajay, E. Robin +7
We report the effect of germanium as n-type dopant on the electrical and optical properties of AlxGa1-xN layers grown by plasma assisted molecular-beam epitaxy. The Al content has…
Improvement of the critical temperature of NbTiN films on III-nitride substrates
Houssaine Machhadani, Julien Zichi, Catherine Bougerol +7
In this paper, we study the impact of using III-nitride semiconductors (GaN, AlN) as substrates for ultrathin (11 nm) superconducting films of NbTiN deposited by reactive magnetron…
Near- and mid-infrared intersubband absorption in top-down GaN/AlN nano- and micropillars
Jonas Lähnemann, David A. Browne, Akhil Ajay +5
We present a systematic study of top-down processed GaN/AlN heterostructures for intersubband optoelectronic applications. Samples containing quantum well superlattices that displa…
