Abstract
Magnetotunneling in a double-barrier diode with a restricted lateral dimension was studied. The zero-field tunneling current shows fine structures supposed to be due to mixing of two-dimensional emitter subbands with one-dimensional subbands in the double-barrier region. Application of a magnetic field causes a depopulation of the current structure. This arises from couplings of electromagnetic subbands with and without conservation of the quantum numbers.
