Abstract

NEMS (Nanoelectromechanical Devices) have been of particular interest in recent years due to a growing set of new applications they offer in domains such as sensitive charge detection, mass sensing and biological imaging. Their size, being reduced down to the nanometer-scale, allows high operating frequencies. Applications in the Gigahertz range have been demonstrated. With devices operating faster the sensitivity is improved. As an example, a sensitivity of 12 Zn/p Hz12 zN⁄√Hz (1zN=〖10〗^(-21) N) N) has been achieved using a carbon nanotube resonator. Moreover, NEMS have very low operating power and high quality factors.

Zinc

Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes.

Zinc oxide

Zinc oxide is an inorganic compound with the formula ZnO. It is a white powder that is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors, and first-aid tapes. Although it occurs naturally as the mineral zincite, most zinc oxide is produced synthetically.

Nanometre

The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American spelling) is a unit of length in the International System of Units (SI), equal to one billionth (short scale) of a metre (0.000000001m) and to 1000 picometres. One nanometre can be expressed in scientific notation as 1e-9m, and as 1/1000000000 metres.
