Transition from Schottky to Ohmic contacts in 2D Ge/GaAs heterostructures with high tunneling probability† The metal–semiconductor (M–S) contact is usually an Ohmic contact or a Schottky contact, which greatly affects the electronic properties of devices, and it remains a huge challenge to realize a low-resistance Ohmic contact in a metal–semiconductor junction (MSJ).
