How Does Quantum Mechanics Influence Electronic Structure?
Quantum mechanics plays a vital role in understanding electronic structure at the nanoscale. Quantum effects become more pronounced as the size of the material decreases. Concepts such as quantum confinement, where the movement of electrons is restricted to small dimensions, and quantum tunneling, where electrons pass through barriers, are critical in nanoscale electronic behavior. These effects can lead to phenomena such as discrete energy levels in quantum dots and enhanced conductivity in nanowires.
