In1 As1 Pt5

InAs–Pt is an intermetallic compound combining indium arsenide (a III–V semiconductor) with platinum, creating a hybrid material that bridges semiconducting and metallic properties. This composition is primarily of research interest for quantum device applications and topological electronic systems, where the combination of a narrow-bandgap semiconductor with a high-Z metal enables tunable band structure and strong spin–orbit coupling effects. InAs–Pt heterostructures and nanostructures are explored in academic and early-stage industrial settings for Majorana fermion detection, quantum computing qubits, and next-generation spintronic devices, though practical device-scale manufacturing remains limited.
