Ion-beam sculpting at nanometre length scales
WebThe distance between the beams is controlled by a high-precision micro-electromechanical system (MEMS). We exploit the mechanical stability of nanobeams under high tensile stress to minimize thermal buckling effects, therefore keeping control of the nanometre-scale separation even at large thermal gradients. Web12 jul. 2001 · We show that ion-beam sculpting can be used to fashion an analogous solid-state device: a robust electronic detector consisting of a single nanopore in a Si3N4 …

Nature 412(6843): 166-169. Abstract Manipulating matter at the nanometre scale is important for many electronic, chemical and biological advances, but present solid-state fabrication methods do not reproducibly achieve dimensional control at the nanometre scale.
WebNanopores (6–30 nm) were fabricated on silicon nitride membranes supported by silicon substrates using a combination of focused ion beam milling and ion beam sculpting. WebAn Ar-ion laser with a wavelength of 514.5 nm was focused on the wire surface using an optical microscope objective lens (100×/0.90 NA) with spatial resolution better than 1 μm. The scattered light from the QD wire was dispersed through a monochromator using a 1200 grooves per mm grating and recorded using a thermoelectrically cooled CCD detector.
WebA nanopore is a pore of nanometer size. It may, for example, be created by a pore-forming protein or as a hole in synthetic materials such as silicon or graphene. When a nanopore …
