The chemical structure of the cell membrane makes it remarkably flexible, the ideal boundary for rapidly growing and dividing cells. Yet the membrane is also a formidable barrier, allowing some dissolved substances, or solutes, to pass while blocking others.
WebElectrons occupy states in the band structure. Each state has the momentum and the energy. The hole is an empty state in the valence band (whereas most of them are occupied with electrons). Momentum of a hole is opposite to electron’s momentum in the respective state, because the hole is the absence of electron.
