Abstract
The electronic structure of nanowires, nanotubes and thin films deposited on a substrate is varied by doping with electrons or holes. The electronic structure can then be tuned by varying the support material or by applying a gate voltage. The electronic structure can be controlled to absorb a gas, store a gas, or release a gas, such as hydrogen, oxygen, ammonia, carbon dioxide, and the like.
Claims20
A method for storing a gas comprising:
- providing a device comprising:
- a support deposited on a gate wherein the support is in electrical communication with the gate;
- a carbon-containing material deposited on the support, wherein the support is in electrical communication with the carbon-containing material and wherein the carbon-containing material is separated from the gate by the support;
- and
- a power supply comprising the gate in electrical communication with the support and the carbon-containing material, wherein the power supply is capable of producing a voltage across the device and wherein the carbon-containing material is configured to adsorb gas responsive to the applied voltage;
- and
- storing a gas by applying a voltage to the device.
