← ScienceWhich outcome occurs inside a quantum dot when increasing the compressive strain on its crystal lattice to shift its electron's probability density?
A)Increased quantum confinement energy✓
B)Decreased electron-hole effective mass
C)Reduced electron tunneling probability
D)Enhanced spin-orbit coupling duration
💡 Explanation
Increased compressive strain reduces the dot's physical dimensions, causing the quantum confinement effect, boosting the electron's kinetic energy because particle-in-a-box energy levels increase. Therefore, energy is increased rather than changing mass or coupling because the dot is compressing.
