Finite-temperature interplay of structural stability, chemical complexity, and elastic properties of bcc multicomponent alloys from ab initio trained machine-learning potentials

Phys. Rev. Materials 5, 073801 (2021) - Published 8 July, 2021

High-throughput finite-temperature phase stability and materials property predictions directly from first-principles are extremely resource demanding. Here, the authors combine density functional theory calculations with accurate machine-learning potentials and an active learning scheme to obtain fast, yet highly accurate interatomic potentials. The approach is used to analyze the bcc-ω phase stability and elastic properties of a series of bcc TiZrHfTax alloys. The phase stability is evaluated by analyzing the projections of atomic displacements from molecular dynamics trajectories revealing fingerprints of bcc-ω martensitic transformations.

Charge carrier dynamics and self-trapping on Sb2S3(100)

Phys. Rev. Materials 5, 075401 (2021) - Published 8 July, 2021

To achieve high power conversion efficiencies in photovoltaic or photoelectrochemical cells, an understanding of the dynamical processes in the electrode materials upon photoexcitation is crucial. Antimony sulfide is a promising candidate material. The authors present time-resolved two-photon photoemission measurements from a Sb2S3(100) single crystal surface. A first laser pulse generates a population of free charge carriers that are probed by a second pulse. Ultrafast relaxation towards the conduction band minimum is followed by a fast decay within 1.3 ps into two longer-lived trap states, self-trapped electrons and self-trapped excitons states, with lifetimes of 27 and 63 ps, respectively. The results support a polaronic self-trapping mechanism by optical phonons.

To achieve high power conversion efficiencies in photovoltaic or photoelectrochemical cells, an understanding of the dynamical processes in the electrode materials upon photoexcitation is crucial. Antimony sulfide is a promising candidate material. The authors present time-resolved two-photon photoemission measurements from a Sb2S3(100) single crystal surface. A first laser pulse generates a population of free charge carriers that are probed by a second pulse. Ultrafast relaxation towards the conduction band minimum is followed by a fast decay within 1.3 ps into two longer-lived trap states, self-trapped electrons and self-trapped excitons states, with lifetimes of 27 and 63 ps, respectively. The results support a polaronic self-trapping mechanism by optical phonons.
