Journal ArticleDOI
Low-noise AlInAsSb avalanche photodiode
TL;DR: In this paper, low-noise avalanche gain from photodiodes composed of a previously uncharacterized alloy, Al 0.7In0.3As0.7, grown on GaSb was reported.
Journal ArticleDOI
Ultrafast dynamics of surface plasmons in InAs by time-resolved infrared nanospectroscopy.
Martin Wagner,Alexander McLeod,Scott J. Maddox,Zhe Fei,Mengkun Liu,Richard D. Averitt,Richard D. Averitt,Michael M. Fogler,Seth R. Bank,Fritz Keilmann,Dimitri Basov +10 more
TL;DR: Time-resolved mid-infrared (mid-IR) near-field spectroscopy of the narrow bandgap semiconductor InAs shows the potential to become an important building block of optically controlled plasmonic devices operating at infrared frequencies.
Journal ArticleDOI
Broadly Tunable AlInAsSb Digital Alloys Grown on GaSb
TL;DR: In this article, the authors used spectra from AlxIn1-xAsySb1-y/GaSb type-II superlattices to determine the direct bandgap and the band offsets as a function of aluminum fraction.
Journal ArticleDOI
Dynamic thermal emission control with InAs-based plasmonic metasurfaces
Junghyun Park,Ju-Hyung Kang,Xiaoge Liu,Scott J. Maddox,Kechao Tang,Paul C. McIntyre,Seth R. Bank,Mark L. Brongersma +7 more
TL;DR: A new approach to actively tailor thermal emission with a reflective, plasmonic metasurface in which the active material and reflector element are epitaxially grown, high-carrier-mobility InAs layers and polarization-dependent and electrically controlled emissivity changes are demonstrated.
Journal ArticleDOI
AlInAsSb/GaSb staircase avalanche photodiode
TL;DR: In this article, a staircase avalanche photodetector (APD) operation using alloys of a rather underexplored material, AlxIn1−xAsySb1−y, lattice-matched to GaSb.
