MoS2-HgTe Quantum Dot Hybrid Photodetectors beyond 2 μm [PDF]

, 2017
Mercury telluride (HgTe) colloidal quantum dots (CQDs) have been developed as promising materials for the short and mid-wave infrared photodetection applications because of their low cost, solution processing and size tunable absorption in the short wave-

On‐Chip Perovskite Coolers

Advanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
Scaling of 3D‐integrated electronics exacerbates thermal bottlenecks, motivating solid‐state on‐chip cooling beyond convection and immersion. This perspective reviews optical refrigeration, electroluminescent cooling, and thermoelectrics for localized, vibration‐free heat removal.

Temperature-driven massless Kane fermions in HgCdTe crystals

Nature Communications, 2016
Kane fermions are predicted to be tunable with external parameters such as temperature. Here, Teppe et al. show a band structure evolution of bulk HgCdTe as temperature is tuned across topological phase transition, demonstrating that Kane fermions change

Mid‐Infrared Intersubband Transitions in p‐Type SiGe Parabolic Quantum Wells

Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
The design, growth, and characterization of hole‐doped Ge‐rich SiGe parabolic quantum wells exhibiting mid‐infrared intersubband transitions are reported. Structural analyses confirm the parabolic compositional profile, while optical spectroscopy supported by tight‐binding simulations demonstrates strong and temperature‐stable absorption up to room ...

Magnetotransport Properties and Subband Structure of the Two-Dimensional Electron Gas in the Inversion Layer of Hg1-xCdxTe Bicrystals [PDF]

, 1990
The electronic and magnetotransport properties of conduction electrons in the grain boundary interface of p-type Hg1-xCdxTe bicrystals are investigated. The results clearly demonstrate the existence of a two-dimensional degenerate n-type inversion layer ...
