42solar cell — a photovoltaic cell that converts sunlight directly into electricity. * * * Any device that directly converts the energy in light into electrical energy through the process of photovoltaics (see photovoltaic effect). Solar cells do not use… …
43Ohmic contact — An ohmic contact is a region on a semiconductor device that has been prepared so that the current voltage (I V) curve of the device is linear and symmetric. If the I V characteristic is non linear and asymmetric, the contact is not ohmic, but is… …
44Microelectromechanical system oscillator — Microelectromechanical system (MEMS) oscillators are timing devices that generate highly stable reference frequencies. These reference frequencies are used to sequence electronic systems, manage data transfer, define radio frequencies, and… …
45Microfabrication — Synthetic detail of a micromanufactured integrated circuit through four layers of planarized copper interconnect, down to the polysilicon (pink), wells (greyish) and substrate (green) Microfabrication is the term that describes processes of… …
46Delay composition — Delay composition, also called delay charge or delay train, is a pyrotechnic composition, a sort of pyrotechnic initiator, a mixture of oxidizer and fuel that burns in a slow, constant rate that should not be significantly dependent on… …
47magnesium processing — Introduction preparation of the ore for use in various products. Magnesium (Mg) is a silvery white metal that is similar in appearance to aluminum but weighs one third less. With a density of only 1.738 grams per cubic centimetre, it… …
