Steady Current And Current Density
https://www.electronics-lab.com/article/steady-current-and-current-density/
Introduction Many practical applications and devices are based on the principles of static electricity. However, electricity was destined to become an inseparable part of our daily lives when scientists learned how to produce a continuous flow of charge for relatively long periods using batteries. The battery, or voltaic cell, was invented in 1800 by Italian […]
Semiconductor Theory
https://www.electronics-lab.com/article/semiconductor-theory/
Semiconductor Theory As it is obvious from the name, semiconductors are those materials having conductivity in between conductors and insulators. Conductors are those materials that impose minimum resistance in the flow of electrons or current. Whereas, insulator materials impose high resistivity and, thus, no current flows in them. As we know, for an atom, there […]
Opto Diode Introduces AXUV20HS1 Circular Photodetectors That Detect Electrons to 200 eV
https://www.electronics-lab.com/opto-diode-introduces-axuv20hs1-circular-photodetectors-detect-electrons-200-ev/
Opto Diode Corporation, an ITW company, introduces a high-speed photodetector with a circular active area of 5 mm diameter (typically 20 mm²). It is ideal for high-speed detection of low-energy electrons or X-rays. The AXUV20HS1 is one of several AXUV detectors that feature high performance measurement of photons, electrons, or X-rays. The device features electron detection to 200 […]
Better current with spin electronics
https://www.electronics-lab.com/better-current-spin-electronics/
by Clemens Valens @ elektormagazine.com The ongoing miniaturisation of electronics is expected to reach its limits in the near future. One of the limitations is the size of electrons that are needed in electronic circuits to transport charge from one place to the other, what we usually call ‘current’. To work around this problem a […]
