Abstract
In certain examples, methods and photo-responsive structures are directed to devices involving a diamond-based photoconductive switch having a doped diamond-grown material in the switch. The doped diamond-grown material may be formed from different gases combined on a diamond seed, such that as grown, the diamond-based material manifests a controlled dopant concentration level of a polarity type and over a depth of optical absorption sufficient to ionize the dopants in response to an optical signal.
Claims33
An apparatus comprising:
- a diamond-based photoconductive switch;
- and
- a doped diamond-grown material in the diamond-based photoconductive switch, the doped diamond-grown material being formed from different gases combined on a diamond seed and therefrom manifest a controlled dopant concentration level with dopants of a polarity type and over a depth of optical absorption sufficient to ionize the dopants in response to an optical signal.
A method comprising:
- in a diamond-based photoconductive switch, using a doped diamond-grown material formed from different gases combined on a diamond seed to manifest a controlled dopant concentration level of dopants of a polarity type and over a depth of optical absorption sufficient to ionize the dopants in response to an optical signal, and
- generating, via the diamond-based photoconductive switch manifesting ionization of the dopants, electric current.
