Resolving the band alignment of InAs/InAsSb mid-wave-infrared type-II superlattices
Michał Rygała, Julian Zanon, Andreas Bader +5
In this work, three InAs/InAsSb superlattices with different periods were investigated using photoluminescence and photoreflectance measurements and their band st…
Spatial structure and magnetism of a spin-orbit entangled spin-1 coherent spin center: the manganese neutral acceptor in a III-V semiconductor
Julian Zanon, Michael E. Flatté
A Mn dopant in a III-V semiconductor produces a highly-entangled, coherent triplet ground state not fully captured by single-determinant theories of electron structure. We directly…
Triple V-shaped type-II quantum wells for long wavelength interband cascade lasers
B. Petrović, T. Sato, S. Birner +5
We investigate triple V-shaped type-II quantum wells designed to emit at 6-9 μm wavelength range, consisting of three InAs(Sb) electron quantum wells and two Ga0.6In0.4Sb hole quan…
Imaging the Acceptor Wave Function Anisotropy in Silicon
Manuel Siegl, Julian Zanon, Joseph Sink +5
We present the first scanning tunneling microscopy (STM) images of hydrogenic acceptor wave functions in silicon. These acceptor states appear as square ring-like features in STM i…
