Observability of superconductivity in Sr-doped Bi2Se3 at the surface using scanning tunneling microscope

Mahasweta Bagchi, Jens Brede, and Yoichi Ando

Phys. Rev. Materials 6, 034201 (2022) - Published 7 March, 2022

While the materials family of electron-doped Bi2Se3 has been established as nematic topological superconductors, the observability of superconductivity on their surface has been controversial for over 10 years. Here, the authors try to resolve this longstanding issue with extensive STM study of high-quality SrxBi2Se3 crystals. Based on their results they propose that superconductivity cannot reach the surface when the topological surface states are intact, but it becomes observable when the topological surface states are destroyed due to strain. In particular, contamination of the STM tip with micrometer-sized flakes of strained SrxBi2Se3 can cause spurious observation of superconductivity.

Quasiparticle energies and optical excitations of 3C-SiC divacancy from GW and GW plus Bethe-Salpeter equation calculations

Weiwei Gao, Felipe H. da Jornada, Mauro Del Ben, Jack Deslippe, Steven G. Louie, and James R. Chelikowsky

Phys. Rev. Materials 6, 036201 (2022) - Published 17 March, 2022

The authors study the divacancy in 3C-SiC, a promising system for quantum information or sensing applications, using large-scale GW plus Bethe-Salpeter equation simulations of nearly 1000 atoms. Notably, in contrast to the widely studied diamond NV center, low-energy excitonic states of 3C-SiC divacancy show substantial characters of transitions from localized defect states to continuum states. Some defect states that contribute to the low-energy excitations significantly hybridize with conduction bands. This work quantitatively determines the quasiparticle energies of defect states and zero-phonon line energy, emphasizing the importance of frontier conduction bands on the low-energy excitons of 3C-SiC divacancy.
