Micro-4PP installed in a cryostat containing superconductor magnet for applying magnetic field in in situ transport measurements on -In surface.^{[ 12 , 33 ]} (a) Schematic drawing of the UHV apparatus installed with micro-4PP and superconductor magnets. (b)–(d) Temperature and magnetic field dependence of the sheet resistance of -In surface, measured with micro-4PP in the apparatus of panel (a). Both T _c and H _c can be determined from the measured results. Inset of panel (b) is the RHEED pattern of -In surface.
