Diamond source

A diamond nanowire single-photon source.

The development of a robust light source that emits one photon at a time will allow new technologies such as secure communication through quantum cryptography. Devices based on fluorescent dye molecules, quantum dots and carbon nanotubes have been demonstrated, but none has combined a high single-photon flux with stable, room-temperature operation. Luminescent centres in diamond have recently e...

Diamonds on Diamond: structural studies at extreme conditions on the Diamond Light Source.

Extreme conditions (EC) research investigates how the structures and physical and chemical properties of materials change when subjected to extremes of pressure and temperature. Pressures in excess of one million times atmospheric pressure can be achieved using a diamond anvil cell, and, in combination with high-energy, micro-focused radiation from a third-generation synchrotron such as Diamond...

The Initial Insertion Devices for the Diamond Light Source

The first eight DIAMOND beamlines have now been agreed. Insertion devices must be tailored to meet the needs of each of these beamlines and so it is now clear what form the first insertion devices for DIAMOND will take. Six of the devices will be short period, small gap undulators designed to reach between approximately 5 to 20 keV with the use of high harmonics. Four of these devices will take...

A Germanium-Vacancy Single Photon Source in Diamond

Single Crystal Diamond Needle as Point Electron Source

Diamond has been considered to be one of the most attractive materials for cold-cathode applications during past two decades. However, its real application is hampered by the necessity to provide appropriate amount and transport of electrons to emitter surface which is usually achieved by using nanometer size or highly defective crystallites having much lower physical characteristics than the i...
