Supermolecular structures and devices made from same. Semiconductor
materials and devices are manufactured and provided which use controlled, discrete
distribution of and positioning of single impurity atoms or molecules within a
host matrix to take advantage of single charge effects. Single-dopant pn junctions
and single-dopant bipolar cells are created. Each bipolar cell can function as
a bistable device or an oscillator, depending on operating temperature. The cells
can be used alone or in an array to make useful devices by adding an insulating
substrate and contact electrodes.
