"Communication-The Role of the Metal-Semiconductor Junction in Pt-Assisted Photochemical Etching of Silicon Carbide";
ECS Journal of Solid State Science and Technology, 5 (2016), 3; 148 - 150.



English abstract:
Porous 4H-SiC layers were fabricated by photochemical etching of n-type 4H-SiC samples with varying resistivity. An etching
solution of Na2S2O8 and HF was used while Pt deposited at the 4H-SiC surface served as catalyst for the reduction of Na2S2O8.
The contact resistance at the Pt/4H-SiC junction was decreased by annealing and surface near phosphorous doping. This enabled the
porosification of 4H-SiC with photochemical etching.
