Stability of charged density waves in InAs nanowires in an external magnetic field

Abstract

We report on magnetotransport measurements at K in a high-quality InAs nanowire ( kΩ) in the presence of the charged tip of an atomic force microscope serving as a mobile gate. We demonstrate the crucial role of the external magnetic field on the amplitude of the charge density waves with a wavelength of 0.8 μm. The observed suppression rate of their amplitude is similar or slightly higher than the one for weak localization correction in our investigated InAs nanowire.
