Description

Description We grow flawless WS2 crystals through chemical vapor transport (CVT) growth optimization as well as flux growth. Our p-type WS2 crystals are doped with Nb atoms in the 1E17-5E18cm-3 range. These electron-doped vdW WS2 crystals are considered the gold standard in the field of 2D materials.

Features And Benefits

Features And Benefits Doped WS2 crystals are known for their excellent valley electronic properties, perfect crystallization, defect-free structure, extremely narrow PL bandwidth, clean PL spectrum (unbound exciton shoulder), and high carrier mobility.
Note that doping into TMDC greatly reduces the crystallization time (growth rate), so electron-doped TMDCs measure smaller values than undoped (intrinsic) TMDCs.

Application

Application Thousands of scientific articles cite us and use these crystals for scientific accuracy and clear signals.
