Formation of nano-pores in nano-crystalline diamond films

► CVD growth conditions determines morphology and chemical composition of NCD films. ► CVD-nano-crystalline diamond can achieve stiffness close to single crystal diamond. ► Nano-pores can be created in NCD films etching the non-diamond phase. ► Porous nano-crystalline diamond films can be used as molecular filters. ► Thin NCD films are extreme robust and flexible.
