The schematic symbol used for the diode is typically an arrow with a short line across the tip. The cathode is the N-type material and is represented by the tip of the arrow. The anode is the P-type ...

Tunnel diodes are heavily doped P-N diodes in which electron tunneling from the conduction band in the N-type material to the valence band in the P-type region produces a region of negative resistance ...

When looking across the discrete components in your electronic armory, it is easy to overlook the humble diode. After all, one can be forgiven for the conclusion that the everyday version of ...

This second course provides a more detailed description of high-voltage Schottky and p-n diodes, starting with the semiconductor physics background needed to analyze both types of diodes. The main ...

The four-layer diode, also known as a Shockley Diode, is a crystal made of alternating layers of N- and P- type semiconductors. By putting in four layers, instead of the three used in transistors ...

To address this challenge, Yagyu and Kuba’s team are working with Kyoto University on developing new photonic-crystal surface-emitting lasers (PCSELs), a type of laser diode. These contain a ...

Symbols are often similar on different types of map. For example, blue symbols are used for buildings or tourist attractions. Footpaths are usually represented by dotted green lines. You can find ...

There are five main types of life insurance to choose from. Here’s a breakdown of what each one covers. Many, or all, of the products featured on this page are from our advertising partners who ...

Features such as this information centre are identified on the map using symbols. This is a camping and caravan site. And here's a nature reserve. On this map, different types of road are marked ...

It is common for different types of psychologists and therapists to develop an eclectic toolbox of skills that draw from multiple approaches.These often include techniques from major therapy types ...

While Alzheimer's disease is the most common form of dementia, there are also other common types such as vascular dementia, Lewy body dementia and Frontotemporal dementia. There are also rarer types ...
