Reducing strain fluctuations in quantum dot devices by gate-layer stacking

Autor: Frink, Collin C. D., Woods, Benjamin D., Losert, Merritt P., MacQuarrie, E. R., Eriksson, M. A., Friesen, Mark

Nanofabricated metal gate electrodes are commonly used to confine and control electrons in electrostatically defined quantum dots. However, these same gates impart a complicated strain geometry that affects the confinement potential and potentially i
