CVD-WSe2单层薄膜，1cm x 1cm square shaped
Description:
This product contains full area coverage WSe2 monolayers on c-cut sapphire substrates. Sample size measures 1cm in size d the entire sample surface contains monolayer thick WSe2 sheet. Synthesized full area coverage monolayer WSe2 is highly luminescent d Ram spectroscopy studies also confirm the monolayer thickness (please see the technical specifications)
Growth method: Our compy synthesizes these monolayers using chemical vapor deposition (CVD) using highest purity (6N) gases d precursors in semiconductor grade facilities to produce crystalline d large domain size samples (1-50um). This is unlike commonly used MOCVD process wherein defects are very very large d domain sizes are small (10nm-500nm). Our samples are always highly luminescent d highly crystallized
