Intersubband spectroscopy probing higher order interminiband transitions in AlN-GaN-based superlattices

We investigate midinfrared intersubband photodetectors based on short-period AlN/GaN superlattices with different quantum well thicknesses. Band structure calculations, as well as optical transmission and photovoltage measurements, underline the importance of higher order interminiband transitions. In particular, it was found that optical transitions between the second and third minibands benef...

Effect of doping on the intersubband absorption in Si- and Ge-doped GaN/AlN heterostructures.

In this paper, we study band-to-band and intersubband (ISB) characteristics of Si- and Ge-doped GaN/AlN heterostructures (planar and nanowires) structurally designed to absorb in the short-wavelength infrared region, particularly at 1.55 μm. Regarding the band-to-band properties, we discuss the variation of the screening of the internal electric field by free carriers, as a function of the dopi...

GaN/AlGaN strain-balanced heterostructures for near-IR quantum well photodetectors: Final report Contract: FA8655-02-M4006

This is the final report for a 1-year project funded by the European Office of Research and Development (EOARD). In this work GaN/AlGaN strain-balanced heterostructures have been designed for near-infrared absorption through intersubband transitions. By making use of existing collaborations with workers at the University of Sheffield and UMIST the semiconductor samples have been grown, characte...

Temperature stability of intersubband transitions in AlN/GaN quantum wells

Temperature dependence of intersubband transitions in AlN/GaN multiple quantum wells grown with molecular beam epitaxy is investigated both by absorption studies at different temperatures and modeling of conduction-band electrons. For the absorption study, the sample is heated in increments up to 400◦C. The self-consistent Schrödinger-Poisson modeling includes temperature effects of the band-ga...
