Occurrence of the collective Ziman limit of heat transport in cubic semiconductors: scattering channels and size effects
Jelena Sjakste, Maxime Markov, Raja Sen +2
In this work, we discuss the possibility of reaching the Ziman conditions for collective heat transport in cubic bulk semiconductors, such as Si, Ge, AlAs and AlP. In natural and e…

Thermoelectric properties of semimetals
Maxime Markov, Emad Rezaei, Safoura Nayeb Sadeghi +2
Heavily doped semiconductors are by far the most studied class of materials for thermoelectric applications in the past several decades. They have Seebeck coefficient values which…

Breakdown of Herring's processes in cubic semiconductors for sub-terahertz longitudinal acoustic phonons
Maxime Markov, Jelena Sjakste, Nathalie Vast +3
In the present work we explain the anomalous behavior of the attenuation of the longitudinal acoustic phonon in GaAs as a function of the phonon energy in the sub-THz domain. T…
