Description
The extended X-ray absorption fine structure (EXAFS) of crystalline InP was measured in the temperature range of 20-295 K. Structural parameters were determined for the first, second and third nearest neighbor (NN) shells. The Debye-Waller factors increase as functions of both radial distance and temperature. The first NN Debye-Waller factor increases slowly with temperature whereas those for the second and third NN shell increase significantly. The influence of correlated motion on the...[Show more]

dc.description.abstract | The extended X-ray absorption fine structure (EXAFS) of crystalline InP was measured in the temperature range of 20-295 K. Structural parameters were determined for the first, second and third nearest neighbor (NN) shells. The Debye-Waller factors increase as functions of both radial distance and temperature. The first NN Debye-Waller factor increases slowly with temperature whereas those for the second and third NN shell increase significantly. The influence of correlated motion on the vibrational behavior of the different shells is readily evidenced. Fitting an Einstein model to the first NN Debye-Waller factor yields an Einstein temperature ΘE = 394 ± 8 K, compared to a value of ΘE = 360 ± 24 K for GaAs. Debye temperatures reported for InP vary between 220 and 440 K depending on the temperature and method of determination. | |
