Unraveling Band‐Tail Effects on Temperature‐Dependent Emission in GaAsBi via Photoluminescence

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
An innovative dual‐spectroscopy approach resolves the debate over GaAsBi's emission temperature sensitivity. By combining temperature‐dependent photoluminescence and transmission spectroscopy, the method decouples the contributions of band‐tail states from the intrinsic band‐edge behavior.

Electrical Properties of Midwave and Longwave InAs/GaSb Superlattices Grown on GaAs Substrates by Molecular Beam Epitaxy

open access: yesNanoscale Research Letters, 2018
In the present work, we report on the in-plane electrical transport properties of midwave (MWIR) and longwave infrared (LWIR) InAs/GaSb type-II superlattices (T2SLs) grown by molecular beam epitaxy (MBE) system on GaAs (001) substrate.

Enhancing Stability at High Temperature in GaSb‐Based Phase‐Change Materials via Carbon Introduction

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 2, February 2026.
Introducing carbon in GaSb alloys boosts thermal stability of the amorphous phase. Crystallization temperature rises, grains shrink, Sb segregation drops, and compressive strain forms. Amorphous phase stays stable to ∼270°C, with 10 times higher electrical contrast and low‐density change (<4%), making these alloys promising for high‐temperature, high ...

Optical Properties of GaSb Nanofibers

open access: yesNanoscale Research Letters, 2011
Amorphous GaSb nanofibers were obtained by ion beam irradiation of bulk GaSb single-crystal wafers, resulting in fibers with diameters of ~20 nm. The Raman spectra and photoluminescence (PL) of the ion irradiation-induced nanofibers before and after ...

Surface State Passivation and Optical Properties Investigation of GaSb via Nitrogen Plasma Treatment

open access: yesACS Omega, 2018
GaSb is one of the most suitable semiconductors for optoelectronic devices operating in the mid-infrared range. However, the existence of GaSb surface states has dramatically limited the performance of these devices.

Correlated X‐Ray and Electron Microscopies of a Single Biphasic GaAs Nanowire

open access: yesSmall Methods, Volume 10, Issue 3, 9 February 2026.
Nano‐focused scanning X‐ray diffraction microscopy at a synchrotron light source, combined with transmission electron microscopy, reveals a clear correlation between the nanoscale distribution of cubic and hexagonal segments in a GaAs nanowire with subtle variations in inter‐reticular spacing, bending, and twisting.

Crystalline GaSb-core optical fibers with room-temperature photoluminescence

open access: yes, 2018
Glass-clad, GaSb-core fibers were drawn and subsequently laser annealed. The as-drawn fibers were found to be polycrystalline, possess Sb inclusions, and have oxide contamination concentrations of less than 3 at%. Melting and resolidifying regions in the

Intervalley scattering in terahertz quantum cascade lasers with GaSb and InGaSb wells

open access: yesAIP Advances, 2018
We theoretically study the performance of terahertz quantum cascade lasers (THz-QCLs) with GaSb wells and InxGa1−xSb wells. The results of rate-equation calculations reveal that the intervalley scattering of electrons from the Γ valley to the L valley in
