Abstract Quantum transport at elevated temperatures is essential for unveiling novel physics and developing quantum devices. Here, we report quantum linear magnetoresistance in the Weyl semiconductor tellurium at temperatures from 40 to 300 K under magnetic fields up to 60 T. The inverse temperature dependence of the linear slopes for both transverse and longitudinal magnetoresistance provides clear evidence that the linear magnetoresistance originates from phonon scattering in the quantum limit.

Abstract Phase engineering of two-dimensional transition metal dichalcogenides (2D-TMDs) offers opportunities for exploring unique phase-specific properties and achieving new desired functionalities. Here, we report a phase-selective in-plane heteroepitaxial method to grow semiconducting H-phase CrSe2. The lattice-matched MoSe2 nanoribbons are utilized as the in-plane heteroepitaxial template to seed the growth of H-phase CrSe2 with the formation of MoSe2-CrSe2 heterostructures.
