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.
Claims18
A method for storing and releasing a gas comprising:
- providing a device comprising:
- a support deposited on a gate wherein the support is in electrical communication with the gate;
- a material deposited on the support, wherein the support is in electrical communication with the material and wherein the material is separated from the gate by the support;
- and
- a power supply comprising the gate in electrical communication with the support and the material, wherein the power supply is capable of producing a voltage across the device and wherein the material is configured to adsorb the gas responsive to the applied voltage;
- storing the gas for a storage time by applying a voltage to the device, wherein the storage time is between 2 and 48 hours;
- and
- releasing the gas by decreasing the voltage.
