InAs/GaSb
InAs/GaSb is a type of superlattice material composed of alternating layers of Indium arsenide (InAs) and Gallium antimonide (GaSb). This material system has garnered significant attention in the field of Quantum Physics due to its unique electronic properties and potential applications in quantum computing and optoelectronic devices.
