Counting electrons one by one - Measurement of very small electrical currents (COUNT)

Project ID: G6RD-CT-1999-00046
Funded under: FP5-GROWTH


The ongoing process of downscaling the size, and reducing the dissipation, of integrated circuits in electronics, particularly those which are portable and battery operated, is leading to the reduction of the electrical currents that flow through these circuits.The challenge of measuring and controlling such small (sub nano-ampere) electrical currents is becoming more and more important to the electronics industry.

Using present day nanotechnology techniques, electronic devices can be fabricated down to sizes that enable the manipulation of individual electrons. High-speed operation of these nano-devices makes them suitable for use not only as high-precision instruments for measuring very small electrical currents, but also to produce a standard of current (ampere) that is based on fundamental constants, and therefore independent of time, location and environmental conditions.

This project summary is one of a series featured in the nanotechnology projects showcase on CORDIS:
