of the forbidden band gap. Direct or indirect transition. 3) Optical transition producing bound electron-hole pair (excitons), requiring less energy than to produce a free electron-hole pair by the system. For free carriers, excitons should be thermally dissociated. The excitons can recombine with the emission of light or phonons.

Gap junctions are a type of cell junction in which adjacent cells are connected through protein channels. These channels connect the cytoplasm of each cell and allow molecules, ions, and electrical signals to pass between them. Gap junctions are found in between the vast majority of cells within the body because they ... Structurally, however, gap junctions and plasmodesmata are quite different. In vertebrates, gap junctions develop when a set of six membrane proteins called connexins form an elongated, donut-like structure called a connexon.
