Event Details

Antimonide-based III-V semiconductors are a unique group of narrow bandgap materials with the maturity level to yield industrial-scale, high-quality devices while also serving as a platform for basic science investigations. Heterostructures made from these compounds feature small energy gaps, less than 0.3 eV, corresponding to optical transitions in the infrared and terahertz regimes. As a result, they have tremendous potential in applications such as detectors, lasers, photovoltaic cells, and spectroscopy. In the field of infrared detection and imaging, antimonide-based materials have emerged as a serious alternative to the incumbent state-of-the-art Mercury Cadmium Telluride due to its superior “–ilities”: uniformity, stability, scalability, manufacturability, affordability. Significant investment in the field of infrared detection over the past three decades has established a sustainable ecosystem for narrow bandgap III-Vs. This in turn provides a technological boost for the advancement of quantum information science with the realization of higher quality materials and better fabrication protocols for micro/nano quantum devices. These narrow bandgap compound semiconductors, comprised of heavy constituent atoms with large spin orbit coupling strengths, offer many advantages in spintronics and semiconductor-based qubit technologies. This talk will summarize HRL’s research and development activities in antimondide-based semiconductors for infrared and quantum applications.
