Anomalies in thickness measurements of graphene and few layer graphite crystals by tapping mode atomic force microscopy

Experimental Studies of Triangular Lattice Antiferromagnets with<i>S</i>=1/2: NaTiO₂and LiNiO₂

Real triangular lattice antiferromagnet with S =1/2 has been long-awaited since Anderson pointed out that its ground state might be a quantum liquid-like state rather than the N...

Charge Density Wave State of Two-Dimensional Electrons in Strong Magnetic Fields

Charge density wave (CDW) states of a two-dimensional electron system occupying only the lowest Landau subband are investigated at T =0 by the Hartree-Fock approximation. It is ...

Effects of Higher Landau Levels and Valley Degeneracy on Charge Density Wave Instability of Two-Dimensional Electrons in Strong Magnetic Fields

A transition temperature to the charge density wave (CDW) state is calculated by the mean field approximation for a two-dimensional electrons in strong magnetic fields. Firstly ...
