Figure 1From: Macroporous silicon for high-capacitance devices using metal electrodesCapacitors’ macroporous silicon microstructure. Detailed SEM view of the macroporous silicon structure fabricated using electrochemical etching. (A) A general view of the etched pores: 3-μm-diameter cylinders and 240-μm depth. (B) A close-up view of the pores' head and the insulating SiO2 layer thermally grown.Back to article page
