Electron Beam Assisted Chemical Etching of Single Crystal Diamond Chips (1st Report)

Crystallographic Orientation Dependent Reactive Ion Etching in Single Crystal Diamond.

Sculpturing desired shapes in single crystal diamond is ever more crucial in the realization of complex devices for nanophotonics, quantum computing, and quantum optics. The crystallographic orientation dependent wet etch of single crystalline silicon in potassium hydroxide (KOH) allows a range of shapes to be formed and has significant impacts on microelectromechanical systems (MEMS), atomic f...

Single-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...

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...

Etching with Electron Beam Generated Plasmas

Single 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...
