More than a decade of growth optimization in chemical vapor transport （CVT） as well as flux growth lead to our flawless MoS2 crystals.

More than a decade of growth optimization in chemical vapor transport (CVT) as well as flux growth lead to our flawless MoS2 crystals. Our p-type MoS2 crystals are doped with Nb atoms at 1E17-5E18cm-3 range. These electronically doped vdW MoS2 crystals are treated as gold standards in 2D materials field. MoS2 crystals from 2Dsemiconductors are known for its superior valleytronic performance, perfect crystallization, defect free structure, extremely narrow PL bandwidths, clean PL spectra (free of bound exciton shoulders), and high carrier mobility. Thousands of scientific articles have cited us and used these crystals for scientific accuracy and clean signals. Please also see our n- and p-type MoS2 crystals doped with Au, Re, Nb, or other transition metal atoms.

Please note that doping into TMDCs greatly reduce the crystallization time (growth speeds), thus electronically doped TMDCs measure smaller than undoped (intrinsic) TMDCs.

Our company essentially provides doping for almost any layered materials including MoS2 crystals. P-type MoS2 samples are doped by Nb atoms at ~2E17cm-3 levels. Crystallinity, electronic, and optical quality have been perfected through our prefected material synthesis techniques. Purity is at 6N (99.9999%). If you need other dopants such as Co, Ni, Re, Nb, Au, and other metals please contact us via
