Filling of second quantum-size subband of a 2D hole gas at a Si(110) surface

A change in the state density of a gas of 2D carriers upon the filling of the next quantum-size subband has been observed directly by the method of capacitance spectroscopy. The carrier g-factor is estimated on the basis of the Shubnikov-de Haas oscillations. A "pinning" of the bottom of a subband near the Fermi level has been observed.
