Employees of the University of Pennsylvania have developed a method of applying a cadmium selenide nanocrystals on flexible plastic substrates . Scientists demonstrated inverter circuit, amplifier and a ring oscillator were realized by trickling to the previously applied to the plastic layers of electrodes and wires.
Scheme made by this method may not work on the voltage of a few volts, and, as noted by the developers, the charge carriers in them 22 times more mobile than in practice that they are now amorphous silicon. Another benefit is the lower application temperature, allowing designers to experiment with different types of plastic, without the risk of melt down. Thus, the use of silicon nanocrystals selenide has a number of compelling benefits to create electrical circuits: flexibility, the relative ease of production and low power consumption.
