Our MoWSe2 alloys with the chemical formula MoxW(1-x)Se2 crystals perfectly crystallize in 2H phase and come at different alloy ratios x. Our crystals are grown using two different techniques through chemical vapor transport (CVT) or flux zone growth (see description of these two methods below) and their composition values were determined by XPS, SAED, and EDS measurements.. These crystals all possess extremely narrow PL bandwidths, display clean PL spectra, high carrier mobility, extremely clean and sharp XRD peaks, and negligible amount of defects (see published results as well as CVT vs. Flux based methods below ). These crystals come with guaranteed alloying and valleytronic response, sharp PL, and good electronic response.

Important advantages of our crystals

1. Crystals come fully characterized using macro, micro, and nanoscale measurements (see below)

2. Thanks to our improved flux zone growth method, our crystals are homogeneously alloyed which means across the specimen you will only find one particular x composition.

3. No separation: Phase separation is commonly observed in 2D TMDCs alloys when cooling profiles are not controlled carefully. Our R&D team has worked over five (5) years to solely solve this problem.
