To the rescue of those 1950s designers came the humble diode. They were cheaper and far more reliable than a point-contact transistor, and capable of forming AND and OR gates with only resistors ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley ...

These home made transistors sacrifice a point contact diode to get the small chip of germanium, and form the other two electrodes with metal foil glued to paper. Given that germanium point contact ...

Bipolar devices, such as pn diodes and bipolar junction transistors, hold promising potential in the high-power electronics ...

This kind of thinking would be as important as science for the invention of the transistor ... Fleming made a vacuum tube known today as a diode. Then the diode was known as a "valve," because ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

Graduate level courses in physical optics, lasers, and completion of semiconductor devices specialization (ECEA 5630 Semiconductor Physics, ECEA 5631 Diode: Junction and Metal Semiconductor Contact, ...

After analysis of the operating constraints of the circuit, the choice was made in favour of NLVT transistor configured as a diode. The design and optimization of the circuit is presented as well as ...

Braun's 'cat's whisker' diodes are notoriously unreliable because ... The same is true for the point contact transistor invented in 1947 at Bell Laboratories. With the arrival of the bipolar ...
