Yes, a material can have both direct and indirect band gap. If the absorption coefficient of a material rapidly increase with increase photon energy, the band energy, is called direct band gap energy.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. When the pores, or “doughnut holes,” of connexons in adjacent animal cells align, a channel forms between the cells.

The band gap is called "direct" if the crystal momentum of electrons and holes is the same in both the conduction band and the valence band; an electron can directly emit a photon. In an "indirect" gap, a photon cannot be emitted because the electron must pass through an intermediate state and transfer momentum to the crystal lattice. american funds balanced funds Note: Since your browser does not support JavaScript, you must press the button below once to proceed.
