Niobium atoms are perfectly incorporated into ReS? matrix. These alloys are not phase separated meaning Nb and Re atoms randomly distributed throughout the crystals. Nb composition varies from slim am

Our newest class of material: Sb2xAs2(1-x)S3 comes in perfect 1:1:3 stoichiometry consisting of Sb-Sb-S3 atoms. After 34 growth trials in a year, perfect stoichirometry, large single crystal domain si

Synthetic MoS2 crystals have been I2 (iodine) intercalated to achieve p-type doping. Crystal size measures ~1cm in size and the product is ready for exfoliation

High purtiy WS2 crystals have been I2 (iodine) intercalated to achieve p-type doping. Crystal size measures 0.5cm and larger in size and the product is ready for exfoliation

Environmentally stable anisotropic transition metal trichalcogenide material TaS3 is available at 2Dsemiconductors USA.

Natural MoS2 is an indirect gap semiconductor (1.2 eV) but becomes highly luminescent in the monolayer from at 1.9 eV (quasi-particle / optical band gap).
