hydrogen-like bond state, the exciton. The spectrum of free Wannier–Mott excitons in bulk crystals is described by a Rydberg series with an effective Rydberg constant given by the reduced effective mass and the dielectric constant. A small dielectric constant and large effective mass yield a localizacquisition 发表于 2025-3-23 16:48:50

Shashank Jain called insulators. Metallic conductivity is typically between 10. and 10. (Ω cm)., while typical insulators have conductivities of less than 10. (Ω cm).. Some solids with conductivities between 10. and 10. (Ω cm). are classified as . However, substances such as alkali-halides whose conductivity isFER 发表于 2025-3-24 11:33:14

h respect to the exciton state. The binding energy of all excitonic quasiparticles is significantly enhanced in low-dimensional semiconductors. Basic features of confined excitons with strongest transitions between electron and hole states of equal principal quantum numbers remain similar. The three容易懂得 发表于 2025-3-24 22:02:05

When phase effects can be neglected, the transport of spin-polarized carriers is described by a two-current model as
