Nanoelectromechanical systems or NEMS are similar to Microelectromechanical systems (MEMS) but smaller. They hold promise to improve abilities to measure small displacements and forces at a molecular scale, and are related to nanotechnology and nanomechanics. Brian Samuel Epstein (September 19, 1934 – August 27, 1967) was a Jewish-English businessman, best known as the manager of The Beatles. ... A mite less than 1 mm on a MEMS device. ... Buckminsterfullerene C60, also known as the buckyball, is the simplest of the carbon structures known as fullerenes. ...


There are two approaches most researchers accept as standard paths to NEMS. The top-down approach can be summarized as “a set of tools designed to build a smaller set of tools”. For example, a millimeter sized factory that builds micrometer sized factories which in turn can build nanometer sized devices. The other approach is the bottom-up approach, and can be thought of as putting together single atoms or molecules until a desired level of complexity and functionality has been achieved in a device. Such an approach may utilize molecular self-assembly or mimic molecular biology systems. Properties For alternative meanings see atom (disambiguation). ... In science, a molecule is the smallest particle of a pure chemical substance that still retains its chemical composition and properties. ... An example of a molecular self-assembly through hydrogen bonds reported by Meijer and coworkers in Angew. ... Molecular biology is the study of biology at a molecular level. ...


In 2000, the first Very Large Scale Integration (VLSI) NEMS device was demonstrated by researchers from IBM[1]. Its premise was an array of AFM tips which can heat/sense a deformable substrate in order to function as a memory device. In 2007, the International Technical Roadmap for Semiconductors (ITRS)[2] contains NEMS Memory as a new entry for the Emerging Research Devices section; an indication that the semiconductor industry is actively considering the technology for implementation in the near (15 years) future.


A combination of these approaches may also be used, in which nanoscale molecules are integrated into a top-down framework. One such example is the carbon nanotube nanomotor. A nanomotor is a molecular device capable of converting energy into movement and forces on the order of the pico-newtons. ...

Microelectromechanical Systems (MEMS) is the technology of the very small, and merges at the nanoscale into "Nanoelectromechanical Systems" (NEMS) and Nanotechnology.
By changing the balance it is possible to influence the anisotropy of the etching, since the chemical part is isotropic and the physical part highly anisotropic the combination can form sidewalls that have shapes from rounded to vertical.
A schematic of a typical reactive ion etching system is shown in the figure below.
