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…

Recent Progress in Proximity Coupling of Magnetism to Topological Insulators
Semonti Bhattacharyya, Golrokh Akhgar, Matt Gebert +3
Inducing long-range magnetic order in three-dimensional topological insulators can gap the Diraclike metallic surface states, leading to exotic new phases such as the quantum anoma…

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…
