A vacuum suitcase transfer infrastructure will be developed to transfer successful devices of projects 3.1 and 3.2 to advanced scanning tunneling spectroscopy set-ups. Phase-biased experiments will be developed and equipped with tunnel probe read-out. Corbino-disk type experiments will be performed where Majoranas are swapped at high frequency while probing the tunneling density of states. Furthermore, the zero-energy modes will be characterized by shot-noise measurements.
