New “Nanodiamond” book published


The exceptional mechanical, optical, surface and biocompatibility properties of nanodiamond have gained it much interest. Exhibiting the outstanding bulk properties of diamond at the nanoscale in the form of a film or small particle makes it an inexpensive alternative for many applications.

Nanodiamond is the first comprehensive book on the subject. The book reviews the state of the art of nanodiamond films and particles covering the fundamentals of growth, purification and spectroscopy and some of its diverse applications such as MEMS, drug delivery and biomarkers and biosensing. Specific chapters include the theory of nanodiamond, diamond nucleation, low temperature growth, diamond nanowires, electrochemistry of nanodiamond, nanodiamond flexible implants, and cell labelling with nanodiamond particles.

Edited by a leading expert in nanodiamonds, this is the perfect resource for those new to, and active in, nanodiamond research and those interested in its applications.

 

European Research Council awards Consolidator Grant to CDF


Oliver Williams, Principal Investigator of Cardiff Diamond Foundry has been awarded a Consolidator grant of €2.73M for the development of “Superconducting Diamond Quantum Nano-Electro-Mechanical Systems.

Coherent Anti-Stokes Raman Spectroscopy of Nanodiamond particles


A recent collaboration with Prof Langbein in Physics, Prof Borri’s group and collaborators within Cardiff Biosciences has lead to the development of Coherent Anti-Stokes Raman Spectroscopy of Nanodiamond particles.

WASPS Poised to Bring Tunable Sources for Quantum Communications


The European Commission-funded Wavelength-tunable Advanced Single Photon Sources (WASPS) program aims to develop a new generation of triggered single-photon sources based on diamond defects coupled to novel optical resonators. The devices in development promise a range of high specifications including ambient-temperature operation, making them ideal for commercial and industrial settings. The three-year program (running from November 2013 to October 2016) involves a consortium of six European research groups.

The WASPS consortium comprises research groups at Oxford University, Bristol University and Cardiff University in the U.K.; Saarland University in Saarbrücken, Germany and Ludwig Maximilians University in Munich; and the National Center for Scientific Research (CNRS) in Grenoble, France. Construction and testing of the devices are being led by professor Jason Smith in Oxford, professor John Rarity in Bristol, professor Dr. Christoph Becher in Saarbrücken and Dr. David Hunger in Munich. Dr. Oliver Williams leads the Cardiff team, which synthesizes the defect-containing diamond materials by using chemical vapor deposition, and Dr. Alexia Auffèves at CNRS in Grenoble leads the theoretical treatment of the devices.

Quantum Design PPMS


We have recently installed a new Physical Property Measurement System (PPMS) from Quantum design (Evercool II). Funded by our ERC consolidator grant.

This system includes a 9T magnet with DC Magnetism, AC Susceptibility, Resistivity, Vibrating Sample Magnetometer etc. This extends our dilution refrigerator (BlueFors 7mK) capabilities for low temperature characterisation of our superconducting diamond.

Carat systems CTS6U


Our Carat Systems CTS6U deposition system for high purity intrinsic diamond is finally operational.  This system is an enhanced 6500 design with conflat sealed windows as well as differentially pumped main seals. It is capable of ppb level nitrogen levels.

Anton Paar SurPASS 3


We have installed an Electrokinetic analyser so we are now able to measure the streaming potential of almost any substrate. This allows us to optimise diamond nucleation on novel materials such as GaN as well as study surfaces in solution.
