Observation of the regions of a 2D electron gas in a layered indium selenide

Quantum oscillations of the resistance of layered я-InSe crystals have been observed at liquid-helium temperature in a magnetic field. These oscillations occur because of the presence in the samples of regions with a 2D electron conductivity.
