Highly Mismatched Semiconductors Alloys: from Atoms to Devices
Highly mismatched alloys (HMAs) are a class of semiconductor materials composed of elements with distinctly different size and/or electronegativity. The alloys exhibit exceptionally strong composition dependence of the electronic band structure parameters, offering a unique opportunity for engineering of the band gaps and band offsets for specific device applications. Emerging applications include lasers and detectors in valuable wavelength ranges, solar cell technologies, terahertz detector technologies, spintronics, and thermoelectrics. This collection provides a forum for scientists and engineers to share their results (ranging from basic science to applications) in this emerging field of study.
