Although many features of the avalanche in a-Se are similar to those in crystalline semiconductors, there are some important distinctions between these phenomena. The most prominent is the temperature dependence of impact ionization rates for electrons “α” and for holes “β” . In crystalline semiconductors, α and β decrease with increasing temperature due to greater phonon scattering at higher temperatures . In contrast, the impact ionization rates in a-Se increase with temperature implying that the mean free path of hot carriers is not controlled by electron–phonon interactions.
50. The crystallization process is manifested by an abrupt change in volume at Tm (melting point), whereas glass formation is characterized by a gradual break in slope. The region over which the change of slope occurs is termed the glass transition temperature. Other thermodynamic quantities such as entropy and enthalpy exhibit a similar behavior. The basic structural difference between an amorphous solid and its crystalline counterpart is the absence of long range order (LRO) in amorphous materials.
Any chain end will be the site of a dangling bond orbital, which in the simplest case will contain an unpaired electron and be electrically neutral relative to the bulk; this dangling bond defect can be written as D or equivalently C1 . Mott et al.  postulated that, following Anderson , electrons residing at D centers should experience a negative Ueff and electron pairing should be energetically favorable as a result of atomic rearrangements. Electron–lattice coupling is strong in amorphous chalcogenides because of the low atomic coordination resulting in a high degree of network flexibility, but more importantly there exist non-bonding, lone-pair p (pi) orbitals at the chalcogen atoms which may be utilized in forming additional bonds, and which are energetically accessible since they are high lying, forming the top of the valence band .
