Induced superconductivity in antimony-based two-dimensional electron gases

Majorana zero modes (MZMs) are a topic of intense research as they constitute the main building block of topological qubits - a qubit type with potentially enhanced coherence time. A promising way to create these quantum states is to couple a one-dimensional (1D) semiconducting segment with spin-orbit interaction to a superconductor, in the presence of an external magnetic field. Growing the active semiconductor as a 2D layer and creating 1Dstructures by top-downprocessing might allowto realize complex multiqubit devices in the future. This thesis explores antimony-based two-dimensional electron gases (2DEGs), known for their favorable material properties, as platforms for topological superconductivity....QRD/Goswami La
