COULOMB TRANSISTOR — A NEW CONCEPT WHERE METAL NANOPARTICLES ARE USED IN PLACE OF SEMICONDUCTOR

COULOMB TRANSISTOR — A NEW CONCEPT WHERE METAL NANOPARTICLES ARE USED IN PLACE OF SEMICONDUCTOR

Electronics News Updates / By

A research group at the University of Hamburg has created a unique coulomb transistor that operates on the principle of the voltage control of the electron band gap in metallic quantum-dot nanoparticles. This Single-electron transistor represents an approach to develop less power-consuming microelectronic devices. It will be possible if industry-compatible fabrication and room temperature operation are achieved.

Printed Two-Dimensional Transistors

Electronics News Updates / By

Researchers from AMBER (Advanced Materials and BioEngineering Research) and Trinity College (Dublin), together with the TU Delft have succeeded in producing printed transistors, which are made solely from two-dimensional nano materials. These materials have characteristics with much promise and, importantly, can also be produced very cheaply. Possible applications for this procedure are food packaging with

Analyzing the vintage 8008 processor from die photos

Electronics News Updates / By

The revolutionary Intel 8008 microprocessor is 45 years old today (March 13, 2017), so I figured it’s time for a blog post on reverse-engineering its internal circuits. One of the interesting things about old computers is how they implemented things in unexpected ways, and the 8008 is no exception. Compared to modern architectures, one unusual

Building a PIN Diode Geiger Counter

Electronics News Updates / By

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,

Latching power switch uses momentary action pushbutton

Latching power switch uses momentary-action pushbutton

Electronics News Updates / By

Most inexpensive pushbutton switches, particularly pc-board-mounting and membrane types, have momentary action. Latching types are often larger and relatively expensive, and they frequently are unavailable in the style you’d like to use. You can thus have a problem if you need a small, inexpensive on/off switch for latching power to a load. The circuit in
