Double-layer-gate architecture for few-hole GaAs quantum dots

The "hole" refers to places in a semiconductor where an electron has been dislodged, thus creating a positive charge. These "holes" or positive charges can be created by heat or imperfections in the creation of the imaging chip. The "holes" are accumulated, or trapped, in a separate semiconductor layer that acts as a diode that prevents them from returning or creating noise. HAD technology suppresses the fixed pattern noise that results from "dark" current that occurs regar… Nettet14. jan. 2024 · Yes, the description is right.
