Buckyballs and diamondoids combined to create molecule-sized diode

Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) claim to have created a molecule-sized electronic component just a few nanometers long that conducts electricity in only the one direction. In essence, a rectifier diode, but one so small that it may one day help replace much bulkier diodes and other semiconductors

Microcontroller based Diode and Bipolar Junction Transistor (BJT) tester

Introduction Most of the digital multimeters these days have built-in features for testing diodes and sometimes transistors. The purpose of this project is to demonstrate a simple way to construct a testing device for diodes and bipolar junction transitors (BJTs) using a microcontroller. The testing algorithm is based on a simple fact that a working

30th Anniversary of the Chernobyl Tragedy – or – Building a PIN Diode Geiger Counter

Exactly 30 years ago a great disaster struck the region of Chernobyl: a nuclear accident occurred that released a large quantity of radioactive particles into the atmosphere. And it is only five years ago that, with the Fukushima Daiichi nuclear disaster, a second similar catastrophic event has taken place. These anniversaries did not directly let me build a PIN Photodiode based Geiger Counter,

Easily measure diode capacitance and reverse recovery

The other day Linda from Purchasing came to me with a problem: Lou from Operations needed to source a replacement for a shorted diode on a switching power supply. The darned thing was marked with a strange part number that no amount of Googling could decipher. There was a recognizable logo marking, but that manufacturer

TPS61093-Q1 Low Input Boost Converter With Integrated Power Diode and Input/Output Isolation

Description The TPS61093-Q1 is a 1.2-MHz, fixed-frequency boost converter designed for high integration and high reliability. The IC integrates a 20-V power switch, input/output isolation switch, and power diode. When the output current exceeds the overload limit, the isolation switch of the IC opens up to disconnect the output from the input. This disconnection protects
