Description
CVD Sb2Te3
Chemical vapor deposited (CVD) Sb2Te3 films have been synthesized at our facilities in 2019. Bulk Sb2Te3 crystal is a topological insulator which crystallizes in an orthorhombic space group. CVD Sb2Te3 samples measure 1x1cm2 in size and reaches to full coverage. By default it is grown onto souble side polished sapphire, but can also be transferred to SiO2/Si substrates on demand.
