Topological insulators demonstrate tremendous potential in fields of electronics and
magnetism for their unique boundary states that are topologically protected against …

Develo** high-efficiency materials with earth-abundant and low-toxicity elements has
become a popular trend in the field of thermoelectrics. Among these compounds, oxides and …

We present calculations of the electronic and thermal transport properties of graphene
antidot lattices with a finite length along the transport direction. The calculations are based …

We report a new mechanism that does not require the formation of interfacial dislocations to
mediate spiral growth during molecular beam epitaxy of Bi 2 Se 3. Based on in situ scanning …

Designing thermoelectric materials with high figure of merit ZT= S 2 GT/K tot requires
fulfilling three often irreconcilable conditions, that is, the high electrical conductance G, small …

The spin-orbit coupling field, an atomic magnetic field inside a Kramers' system, or discrete
symmetries can create a topological torus in the Brillouin Zone and provide protected edge …

We analyze electronic and phononic quantum transport in zigzag or chiral graphene
nanoribbons (GNRs) perforated with an array of nanopores. Since local charge current …

Large-area topological insulator Bi 2 Te 3 thin films were grown on Al 2 O 3 (0001) using a
two-temperature step molecular beam epitaxy growth process. By depositing a low …

The thermoelectric properties of Cu-doped Cu x Bi 2 Se 3 (x= 0, 0.005, 0.010, 0.015 and
0.020) were investigated in the temperature range of 300 K to 590 K. The results indicate …

We measure gate-tuned thermoelectric power of mechanically exfoliated Bi2Se3 thin films in
the topological insulator regime. The sign of the thermoelectric power changes across the …
