The Physics of Amorphous Solids

Charge carrier localization and metal to insulator transition in cerium substituted (Bi,Pb)-2212 superconductor

“…We have estimated the localization length and most probable hopping distance (R) [22] of the insulating samples, by making use of Eqs. (3)- (5).…”

“…The term exp(−2aR) denotes the probability of finding an electron at a distance R from its initial state and a is the inverse localization length [˛− 1 ] [22].…”

Growth and optical properties of amorphous Be0.13Zn0.38O0.49 thin films prepared by radio frequency magnetron sputtering

“…In brief, the disorder is known to influence the optical properties of amorphous semiconductors [4]. In addition, these amorphous materials and their alloys have many present-day applications such as fiber optic waveguides for communication networks, flexible thin film capacitors, computer-memory elements, antireflection optical coatings [3][4][5]. Often, the problem of the crystal phase segregation which is due to the different crystal structures and large lattice mismatch between the components of a crystalline alloy can not be avoided.…”

“…Amorphous semiconductors are of considerable interest in solid state physics because of the intriguing question of the relation between electronic properties and disorder which relaxes the k-selection rules for the optical transitions [3]. In brief, the disorder is known to influence the optical properties of amorphous semiconductors [4].…”

Structural-dynamic model of 2-biphenylmethanol in an anharmonic approximation

“…The investigation of glass microstructure is an important fundamental area in the physics of the condensed state. The microstructure determines the specifics of the transition of the compound into the amorphous state [13] and the dynamics of its quantum-molecular system components. A complex investigation of the spectra provides reliable information about their structure and dynamics in any phase state, including the amorphous state.…”
