Углеродные пленки на SiC (карбид кремния) получили множество применений, начиная от трибологии до электрического хранения энергии. Образования эпитаксиальных или гетероэпитаксиальных слоев углерода на SiC в мягком растворе, такие как электро-или фотохимические, могут быть интересны для различных областей применения и снижения энергоемкости, что делает процесс совместимым с изготовлением электронных устройств. Исследователи показали формирование углеродного слоя на керамике карбида кремния с помощью электрохимического травления в неводном электролите.

Ученые провели селективное травление кремния Si из карбида кремния SiC в одностадийной реакции с фтористоводородной кислотой (HF) в различных органических растворителях, и исследовали роль полярности, поверхностного натяжения, плотности и вязкости органических растворителей в формировании углеродного слоя. Раствор фтористоводородной кислоты HF и этанола (в соотношении 1:4.6) при малых плотностях тока (10 и 20 мА/см2) позволяет лучше контролировать процесс селективного травления кремния Si с последующим образованием аморфного и упорядоченного углерода на поверхности SiC.
