In this talk. I will discuss the protocol we employ to map the phase space (chemical potential and magnetic field) of these devices to identify regions consistent with topological superconductivity and to extract the topological gap. Further, I will present both simulated and measured phase diagrams of three-terminal devices based on InAs-Al heterostructures, which are consistent with the emergence of topological superconductivity and a topological gap of around 30ueV
