With the dream of creating a paintable semiconductor layer for ad-hoc creation of simple diodes, he’s been experimenting with oxidising copper to make a surface of cupric oxide onto which he can ...

Their dynamic range is therefore limited. Diode-based power sensors extend the power measurement range far below 300 nW. They offer a dynamic range of up to 90 dB. Depending on their implementation, ...

Several techniques exist, but [Wolfgang] over at the Electronic Projects for Fun blog decided to go for the classic method of using a vacuum diode. He describes the design and analysis of a noise ...

Speaking at the LASER World of Photonics event taking place this week in Munich, Germany, three members of the EC-funded “FULLPHASE” team detailed how recent advances in computing power and laser ...

Early diodes only released a little energy, so they emitted infrared light. To make a diode that could produce visible light, scientists had to widen the energy gap. By the early 1970s ...

It may also be possible to make the diode operate as an LED. “My results are not only a direct confirmation of the structural purity of single-walled nanotubes but a strong affirmation of their ...
