Figure 1From: Rectified voltage induced by a microwave field in a confined two-dimensional electron gas with a mesoscopic static vortex(a)A confined 2DEG of size L × L with a classical turning point length L F which contains an insulating region of radius D centered at R (the location of the vanishing wave function). (b) Particles close to the classical turning point L F , represented by the shaded area which satisfy the constraint Π1 = Π2 = 0.Back to article page
