Abstract
Electrical devices which incorporate electrodes coated with carbon nanotubes. An anode is placed in conductive relationship with the coated electrode. A gas medium is placed between the electrode and anode which medium also participates in the transfer of electrons. Using specific gas media in combination with nanotube coated electrodes allows for the production of electromagnetic radiation sources which have extended life, reduced power requirements, and significantly decreased operating temperatures.
Claims15
A carbon nanotube electrical device comprising:
- a) a cathode coated with carbon nanotubes and configured for emitting electrons;
- b) an anode placed in an electrically conductive relationship with the cathode, such that there is a space between the cathode and the anode;
- and
- c) a gas medium placed in the space which participates in the transfer of electrons across the space.
A method for improving the performance of an electrical device having a cathode, placed in a conductive relationship with an anode and having a space filled with either a gas medium that participates in transferring electrons across the space defined therebetween, comprising the step of:
- coating the cathode with carbon nanotubes configured for emitting electrons.
