Which outcome results when modulating control gate voltage on a quantum dot modeled by a delta function potential?

💡 Explanation

When gate voltage is modulated, the potential well's shape (delta function) is altered since the potential is directly proportional to the gate. This in turn leads to shifts in the quantized energy levels of the electron within the quantum dot because of quantum confinement. Therefore, the electron energy level changes, rather than increasing escape, localization, or spin lifetime which arise from other factors.
