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...
متن کاملSingle Crystal Diamond Schottky Photodiode
Thanks to its extreme optical and electronic properties, diamond appears to be a promising semiconducting material for photon detection. Its wide band-gap, 5.5 eV, results in a very low leakage current and its electronic properties as high carrier mobility allow fast time response (J. E. Field, 1979). Besides, it has a large breakdown electric field (∼10 V/┤m), a low dielectric constant (i.e. l...
متن کاملSilicon Vacancy Defects in Diamond as Single Photon Source
For the applications in quantum information and experiments on the foundations of quantum mechanics a robust narrow-band single photon source is desirable. We report on single photon emission from the Silicon Vacancy (SiV) centers in diamond fabricated by ion implantation. Single SiV centers are photostable and have a spectrum consisting of a sharp zero phonon line (FWHM is about 5 nm) at 738 n...
متن کاملNanofluidics of Single-Crystal Diamond Nanomechanical Resonators.
Single-crystal diamond nanomechanical resonators are being developed for countless applications. A number of these applications require that the resonator be operated in a fluid, that is, a gas or a liquid. Here, we investigate the fluid dynamics of single-crystal diamond nanomechanical resonators in the form of nanocantilevers. First, we measure the pressure-dependent dissipation of diamond na...
متن کاملSingle-Crystal CVD-Diamond Detectors Progress Report
Figure 1: Dark current behaviour of BDS samples metallized with sputtered Cr-Au electrodes. The measurements are performed in an electric-field range Emax= ± 3.0 V/μm by controlling dI/dV < 1nA/10V. At E = ± 1 V/μm, low currents of absolute values < 10 pico amps are measured for most of the samples. These are by orders of magnitude lower currents than those obtained from electronic-grade PolyCr...
