Abstract
A method for manufacturing a carbon nanotube (CNT) of a predetermined length is disclosed. The method includes generating an electric field to align one or more CNTs and severing the one or more aligned CNTs at a predetermined location. The severing each of the aligned CNTs may include etching the predetermined location of the one or more aligned CNTs and applying a voltage across the one or more etched CNTs.
Claims20
A device for manufacturing a carbon nanotube (CNT) having a predetermined length, the device comprising:
- at least one pair of first and second electrodes configured to align one or more CNTs between the first and second electrodes;
- an etchant device configured to etch one or more predetermined locations of the one or more CNTs;
- and
- an electronic device configured to generate an electric field between the first and second electrodes to align the one or more CNTs located between the first and second electrodes, and to apply a voltage to sever the one or more CNTs at the one or more predetermined locations.
A device for manufacturing a carbon nanotube (CNT) of a predetermined length, the device comprising:
- at least one pair of first and second electrodes configured to align one or more CNTs between the first and second electrodes;
- a source including a CNT solution configured to dispense the CNT solution between the first and second electrodes, the CNT solution including the one or more CNTs;
- an etchant device configured to etch one or more features at one or more predetermined locations of the one or more CNTs;
- and
- an electronic device configured to generate an electric field between the first and second electrodes to align the one or more CNTs located between the first and second electrodes, and to apply a voltage to sever the one or more CNTs at the one or more predetermined locations.
A device for manufacturing a carbon nanotube (CNT) of a predetermined length, the device comprising:
- a substrate;
- at least one pair of first and second electrodes positioned on the substrate;
- a CNT solution provided on at least a portion of the substrate between the first and second electrodes, the CNT solution including one or more CNTs;
- an etchant device configured to etch one or more predetermined locations of the one or more CNTs;
- and
- an electronic device configured to generate an electric field between the first and second electrodes to align the one or more CNTs located between the first and second electrodes, and to apply a voltage to sever the one or more CNTs at the one or more predetermined locations.
