This product contains full area coverage MoSe2 few-layers that measure ~5 layers in thickness. Sheets are grown through chemical vapor deposition technique onto c-cut double side polished sapphire substrates, but layers c be trsferred onto other substrates by polymer assisted trsfer technique on demd (please select from the drop down menu). The sample measures 1cm2 in size d the entire sample surface contains few-layer thick MoSe2 sheet. Grown few-layers are high-crystalline as evidenced by HR-TEM, Ram, EDS, d XRD measurements. 

Our compy synthesizes these few layers using chemical vapor deposition (CVD) with highest purity (6N) gases d precursors in semiconductor grade facilities. This produces highly crystalline d large domain size samples that rge from 1 to 50 microns in lateral sizes. CVD grown samples from other sources typically use MOCVD or sputtering process wherein carbon contamination is problematic, defect density is extremely large, domain sizes are small (10nm-500nm). Our samples are always highly crystallized, high purity, d perfectly layered.
