Abstract

Electron focusing has been observed in a GaAs/AlGaAs heterojunction, patterned into single and double grids by a combination of electron beam lithography and ion implantation. We report for the first time that the focusing peaks split and separate when a dc current is forced through the double grid. A possible cause of this effect is the acceleration and deceleration of electrons through the grids. Theory of electron focusing has been developed in terms of microscopic transmission probability, with a good agreement between measured and calculated magnetic and electric fields dependences.
