Ballistic Electron Transport Through a Narrow Channel is Quantized Available to Purchase

The electrical conductance of a short and narrow conducting channel is quantized in units of $2e2/h,$ a team of experimenters from the Netherlands recently reported. The effect was independently observed by experimenters at Cambridge University at much the same time as its discovery by the Dutch group. In the new effect the conductance of the channel, which connects two‐dimensional reservoirs of electrons, remains constant at an integral multiple of $2e2/h$ for a range of channel widths but jumps sharply to the next higher integral multiple of $2e2/h$ at some critical values of the width.
