Increased Phase Coherence Length in a Porous Topological Insulator
Alex Nguyen, Golrokh Akhgar, David L. Cortie +11
The surface area of Bi2Te3 thin films was increased by introducing nanoscale porosity. Temperature dependent resistivity and magnetotransport measurements were conducted both on as…
Freestanding n-Doped Graphene via Intercalation of Calcium and Magnesium into the Buffer Layer - SiC(0001) Interface
Jimmy C. Kotsakidis, Antonija Grubišić-Čabo, Yuefeng Yin +12
The intercalation of epitaxial graphene on SiC(0001) with Ca has been studied extensively, yet precisely where the Ca resides remains elusive. Furthermore, the intercalation of Mg…
Quantum Transport in Air-stable Na3Bi Thin Films
Chang Liu, Golrokh Akhgar, James L. Collins +4
Na3Bi has attracted significant interest in both bulk form as a three-dimensional topological Dirac semimetal and in ultra-thin form as a wide-bandgap two-dimensional topological i…
Electronic bandstructure of in-plane ferroelectric van der Waals
James L. Collins, Chutian Wang, Anton Tadich +11
Layered indium selenides () have recently been discovered to host robust out-of-plane and in-plane ferroelectricity in the and ' phases, respectively. In this…
Electric Field-Tuned Topological Phase Transition in Ultra-Thin Na3Bi - Towards a Topological Transistor
James L. Collins, Anton Tadich, Weikang Wu +11
The electric field induced quantum phase transition from topological to conventional insulator has been proposed as the basis of a topological field effect transistor [1-4]. In thi…
Temperature Dependent n-p Transition of 3 Dimensional Dirac Semimetal NaBi Thin Film
Chang Liu, Jack Hellerstedt, Mark T. Edmonds +1
We study the temperature dependence ( K - K) of the longitudinal resistivity and Hall coefficient of thin films (thickness nm) of three dimensional topological Dirac…
