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,
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.

1. 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
1. 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; anda 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; andreleasing the gas by decreasing the voltage. 2. The method of claim 1, wherein the support comprises SiO2 and/or Si. 3. The method of claim 1, wherein the material is one-dimensional. 4. The method of claim 1, wherein the material is two-dimensional. 5. The method of claim 1, wherein the material a carbon-containing material. 6. The method of claim 5, wherein the carbon-containing material is selected from the group consisting of carbon, activated carbon, carbon powder, amorphous carbon, carbon fibers, carbon nanofibers, graphite, carbon films, and combinations thereof. 7. The method of claim 5 wherein the carbon-containing material is about 2 μm in length. 8. The method according to claim 1, wherein the material is selected from the group consisting of metal nanowires, metal films, and combinations thereof. 9. The method according to claim 8, wherein the metal is selected from Al, Ni, Ga, As, their alloys, and combinations thereof. 10. The method of claim 1 wherein the gas is hydrogen, oxygen, carbon dioxide, carbon monoxide, methane, ammonia, NO, or a combination thereof. 11. The method of claim 1 wherein decreasing the voltage comprises decreasing the voltage about 5% to about 50%. 12. The method of claim 1 wherein the power supply is configured to produce a voltage of between −50 V and +50 V across the device. 13. The method of claim 1 wherein the power supply is capable of producing a voltage of between −20 V and +20 V across the device. 14. The method of claim 1 wherein the power supply is capable of producing a voltage of between −15 V and +15 V across the device. 15. The method of claim 1 wherein the power supply is capable of producing a voltage of between −10 V and +10 V across the device. 16. The method of claim 1 wherein the material is doped with a metal. 17. The method of claim 16 wherein the metal is lithium, sodium, or potassium. 18. The method of claim 1 wherein the support comprises a lower part and an upper part and the power supply comprises a negative pole and a positive pole and wherein the negative pole of the power supply comprises the gate and the positive pole of the power supply is connected to the upper part of the support.
