Spin statistics states that one singlet exciton is generated for every three triplet excitons after the recombination of holes and electrons in organic semiconductor materials 1. Light emission can be ...

In a development that will be welcomed by those awaiting the advent of high-brightness pico-projectors, Germany’s Osram Opto Semiconductors (Osram OS) has launched its first diode lasers to emit ...

High-power direct-diode lasers have emerged as a competitive option for applications like cladding, welding and heat treating. Stuart Woods of Coherent explains why the basic construction and ...

The circuit has been designed for transistors to determine whether the pin is emitter, base or collector as well as the type if NPN or PNP polarity, and can also be used in testing diodes. 4011 – a ...
