Shape-and dimension-controlled single-crystalline silicon and sige nanotubes: Toward nanofluidic fet devices

Article abstract of DOI:10.1021/ja808483t

We report here on the formation of robust and entirely hollow single-crystalline silicon nanotubes, from various tubular to conical structures, with uniform and well-controlled inner diameter, ranging from as small as 1.5 up to 500 nm, and controllable wa
