A Surface-conduction Electron-emitter Display (SED) is a flat panel display technology that uses surface conduction electron emitters for every individual display pixel. The surface conduction electron emitter emits electrons, that excite a phosphor coating on the display panel which is similar to the basic concept found in traditional cathode ray tube (CRT) televisions. This means that SEDs can combine the slim form factor of LCDs with the high contrast ratios and can also refresh rates making the picture quality of CRTs better .The researches ....etc

RELAXATION TIME ť
FOR TYPICAL MONO-VALENT METALS
IS SHOWN IN TABLE

The conductivity σ may be obtained experimentally .
Further we can get ť by using eqn given below
σ = ( n*Qe2 *ť )/me ---------(1)
but ť obtained may not be accurate but we will get an idea of magnitude of ť . In a monovalent metal no of free e- /m3 is equals the no of atoms /m3 . From table we find that relaxation time T is of the order of 10-14 sec .Thus we can ....etc

Surface conduction Electron emitter Display


The SED technology has been developing since 1987. The flat panel display technology that employs surface conduction electron emitters for every individual display pixel can be referred to as the Surface-conduction Electron-emitter Display (SED). Though the technology differs, the basic theory that the emitted electrons can excite a phosphor coating on the display panel seems to be the bottom line for both the SED display technology and the traditional ....etc

Single electron tunneling (SET) transistor

ABSTRACT
The chief problem that are faced by chip designers are regarding the size of the chip. According to Moores„¢s Law, the number of transistors on a chip will approximately double every 18 to 24 months. Moore\'s Law works largely through shrinking transistors-the circuits that carry electrical signals. By shrinking transistors, designers can squeeze more transistors into a chip. However, more transistors means more electricity and heat compressed into an even smaller space. F ....etc

An electromagnetic bomb or E-bomb is a weapon designed to disable electronics with an electromagnetic pulse (EMP) that can couple with electrical/electronic systems to produce damaging current and voltage surges by electromagnetic induction. The effects are usually not noticeable beyond 10 km of the blast radius unless the device is nuclear or specifically designed to produce an electromagnetic pulse. Small nuclear weapons detonated at high altitudes can produce a strong enough signal to disrupt or damage electronics many mile ....etc
