Ultrafast measurements of mode-specific deformation potentials of BiTe and BiSe
Yijing Huang, José D. Querales-Flores, Samuel W. Teitelbaum +24
Quantifying electron-phonon interactions for the surface states of topological materials can provide key insights into surface-state transport, topological superconductivity, and p…
Influence of local symmetry on lattice dynamics coupled to topological surface states
Jonathan A. Sobota, Samuel W. Teitelbaum, Yijing Huang +18
We investigate coupled electron-lattice dynamics in the topological insulator Bi2Te3 with time-resolved photoemission and time-resolved x-ray diffraction. It is well established th…
Molecular dynamics simulation of the ferroelectric phase transition in GeTe: displacive or order-disorder?
Đorđe Dangić, Stephen Fahy, Ivana Savić
Experimental investigations of the phase transition in GeTe provide contradictory conclusions regarding the nature of the phase transition. Considering growing interest in technolo…
Temperature induced band convergence, intervalley scattering and thermoelectric transport in p-type PbTe
Ransell D'Souza, José D. Querales-Flores, Jiang Cao +2
Achieving high valley degeneracy (i.e. "band convergence") in a material usually results in considerably enhanced thermoelectric properties. However, it is still unclear why this s…
Photo-induced plasmon-phonon coupling in PbTe
M. P. Jiang, M. Trigo, S. Fahy +19
We report the observation of photo-induced plasmon-phonon coupled modes in the group IV-VI semiconductor PbTe using Fourier-transform inelastic X-ray scattering at the Linac Cohere…
Electronic properties of bismuth nanostructures
Christian König, James C. Greer, Stephen Fahy
The passivation of thin Bi(1 1 1) films with hydrogen and oxide capping layers is investigated from first principles. Considering termination-related changes of the crystal structu…
