Signatures of trivial to topological phase transition in Bi1−xSbx nanocrystals synthesized by microwave assisted solvothermal method

In the present work, influence of variation of Sb doping in Structural, morphological and magneto transport properties of topological insulator Bi1−xSbx nano particles is investigated. As in the case of single crystals, in the range (0.07
