Hydrothermal Synthesis of Tellurium Nanoflakes with Post Growth Thinning

POSTER

Abstract

Tellurium is a hexagonal chiral crystal with covalently bonded left- or right-spiral chains of atoms along the c-axis, with much weaker van der Waals interactions between the chains. The lowest conduction bands exhibit Weyl node crossings with different chiralities at the H and H’ points in the Brillouin zone. We synthesize 40 nm-thick Tellurium nanoflakes via the hydrothermal method, and confirm the quality of our samples with Raman spectroscopy. The flakes were thinned through a basic NaOH- solution with acetone. Thicknesses was measured with Raman spectroscopy, via peak shift, and confirmed using atomic force microscopy.
