Single HfO2stalactite conical nanopore (TEM image, top) out of an array of 30 x 30 = 900 stalactite conical nanopores (TEM image, bottom) on a 400 m2surface of a freestanding SiN membrane. The pores have a base of 100 5 nm and a tip of 18 5 nm, analyzed from random 13 positions in the arrays (FigureS13, Supporting Information).
