✦ Synopsis

The Fourier spectrum of the magnetoresistance oscillations in an Aharonov-Bohm ring using two-dimensional electron gas (2DEG) InAs has been studied from the view point of Berry's phase. The ensemble averaged spectrum of the AB-oscillations shows a splitting of We-peak as well as a splitting of h/2e-peak. Such a splitting in the spectrum is indicative of Berry's phase.
