Epitaxial growth of Ge1−xSnx thin film with Sn composition of 50% and possibility of Ge–Sn ordered bonding structure formation

open access: yesApplied Physics Express
We examined the epitaxial growth of Ge _1− _x Sn _x thin film with x ∼ 0.50 on GaSb(111) substrate using a low-temperature MBE. X-ray diffraction and Raman scattering spectroscopy analyses revealed that the Ge _1− _x Sn _x thin film with x ∼ 0.50 with no

V-Shaped InAs/Al0.5Ga0.5Sb Vertical Tunnel FET on GaAs (001) Substrate With I $_{\text {ON}}=\text {433}\,\,\mu$ A. $\mu$ m $^{-\text {1}}$ at V $_{\text {DS}}= \text {0.5}$ V

open access: yesIEEE Journal of the Electron Devices Society, 2017
We report on the fabrication of a near broken InAs/Al0.5Ga0.5Sb vertical TUNNEL field effect transistor (TFET). The epitaxial structure is grown on a GaAs (001) substrate thanks to large mismatch accommodation at the GaSb/GaAs interface.

Photoluminescence Properties of Type‐II GaSb/GaAs Quantum Rings

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
This study examines the magneto‐optical properties of GaSb/GaAs quantum rings (QRs) using photoluminescence spectroscopy. Recombination dynamics in single‐ and ten‐layer structures are analyzed through activation energy extraction, optical absorption profiling, and observation of a strong excitation‐induced blue shift. Carrier lifetime is also increase

Germanium Laser Power Converters at 1550 nm with Efficiencies Over 30%

open access: yesSolar RRL, Volume 9, Issue 23, December 2025.
Germanium laser power converters convert laser light into electrical power at 1550 nm, offering eye safety and atmospheric transparency. We present improved Ge‐based converters achieving record efficiencies of 30.8% at 6.7 W/cm2. We analyze current limitations and provide a roadmap for efficiencies exceeding 39%, demonstrating the expanding role of ...

Gate-controlled semimetal-topological insulator transition in an InAs/GaSb heterostructure

open access: yes, 2015
We report a gate-controlled transition of a semimetallic InAs/GaSb heterostructure to a topological insulator. The transition is induced by decreasing the degree of band inversion with front and back gate voltages.
