Contribution

It demonstrates the successful growth and characterization of rhombohedral bismuth single crystals exhibiting SdH oscillations, linking crystal quality to quantum oscillation phenomena.

Findings

SdH oscillations observed in resistivity measurements

Confirmation of Fermi surface presence

High-quality single crystal growth verified by XRD, SEM, EDAX

Abstract

The historic de Haas van Alphen effect observed in the late 1950s in CSIR-NPL by J.S. Dhillon and D. Shoenberg in pure bismuth and zinc metal is revisited in this article hrough a single crystalline phase of bismuth crystal, which is observed in terms of resistivity as predicted by Shubnikov de Haas oscillations. The occurrence of oscillations in the transverse magnetic field confirms the presence of the Fermi surface. The single crystal of bismuth is grown through solid-state reaction under an optimized heat treatment whose purity and structural phase are confirmed through XRD, SEM, and EDAX.
