Trapping of electrons around nanoscale metallic wires embedded in a semiconductor medium
Chi Cuong Huynh, R. Evrard, Ngoc Duy Nguyen
We predict that conduction electrons in a semiconductor film containing a centered square array of metal nanowires normal to its plane are bound in quantum states around the centra…
