ABSTRACT
Pronounced asymmetries of electrical properties are observed in nanoelectronic, symmetric GaAs/AlGaAs Y-branches. Finite voltages V[sub l] and V[sub r] applied to the left- and right-hand side branch reservoir of a symmetric, ballistic Y-branch switching device in push–pull fashion (i.e., V[sub l]=-V[sub r]) lead to a negative output voltage V[sub s] of the floating, central stem reservoir located between the two branches. We explain our observations exploiting the ballistic nature of the electron transport in the device. © 2001 American Institute of Physics.
