Single-molecule electronics: Hydrogen bridges the gap
Hydrogen is the smallest and most volatile of all molecules, but it has now proved possible to capture a single hydrogen molecule between two platinum electrodes and measure its conductance. At a temperature of 4.2 K the hydrogen molecule forms a nearly perfect, stable channel for one quantum unit of conductance. The hydrogen bridge can be used as a simple test system for establishing the properties of single-molecule devices.
