Gigantic negative magnetoresistance in a disordered topological insulator
Oliver Breunig, Zhiwei Wang, A. A. Taskin +3
With the recent discovery of Weyl semimetals, the phenomenon of negative magnetoresistance (MR) is attracting renewed interest. While small negative MR can occur due to the suppres…
