Field-effect mobility enhanced by tuning the Fermi level into the band gap of Bi2Se3
Peng Wei, Zhiyong Wang, Xinfei Liu +2
By eliminating normal fabrication processes, we preserve the bulk insulating state of calcium-doped Bi2Se3 single crystals in suspended nanodevices, as indicated by the activated t…
Temperature dependence of Raman-active optical phonons in Bi_2Se_3 and Sb_2Te_3
Y. Kim, X. Chen, Z. Wang +8
Inelastic light scattering spectra of Bi_2Se_3 and Sb_2Te_3 single crystals have been measured over the temperature range from 5 K to 300 K. The temperature dependence of dominant…
77Se NMR Investigation of Fe-doped Bi2Se3
Robert E. Taylor, Hamad M. Alyahyaei, Zhiyong Wang +6
Bismuth selenide is both a thermoelectric material and topological insulator. Defects and dopants create conduction in thermoelectric applications. However, such defects may degrad…
Suspension and Measurement of Graphene and Bi2Se3 Atomic Membranes
Jairo Velasco, Zeng Zhao, Hang Zhang +7
Coupling high quality, suspended atomic membranes to specialized electrodes enables investigation of many novel phenomena, such as spin or Cooper pair transport in these two dimens…
