The process starts with a 2-μm layer of single crystalline 3C-SiC heteroepitaxially grown on a 100-mm wafer of (100) silicon (Si). The 3C-SiC can be grown utilising a two-step carbonisation-based VD process, which has been described in detail elsewhere [ 47 ].
Trimming grid losses with SiC - News
Now on the market are SiC substrates with a diameter of 100 mm, and 150 mm equivalents will soon follow. The quality of these foundations for SiC growth are getting better and better, with the density of micro pipes "“ a type of defect that can kill devices "“ plummeting to just 0.75 cm -2 for a 75 mm wafer.

INTRODUCTION Graphene has attracted attention worldwide and is considered a promising material for industrial appliions. Before the exfoliation of graphene with Scotch tape was reported in 2004 , several groups had exfoliated graphite to thin platelets [2, 3], and identified ‘single-layer graphite’ on noble metal surfaces as grown by chemical vapor deposition (CVD) .
