Aberrations introduced during fabrication degrade the performance of X-ray optics and their ability to achieve diffraction limited focusing. Corrective optics can counteract these errors by introducing wavefront perturbations prior to the optic which

We present direct observation of the electron field emission sites over a large area of polycrystalline diamond using tunnelling atomic force microscopy. Any effects of surface topography have been reduced by measuring polycrystalline samples which h

A detailed investigation of electron emission from a set of chemical vapour deposited (CVD) diamond films is reported using high-resolution PeakForce-controlled tunnelling atomic force microscopy (PF-TUNA). Electron field emission originates preferen

We present the dc operation of hydrogen-terminated diamond field-effect transistors (FETs) with gate lengths of 1 μm to 50 nm. The 50-nm device metrics include a maximum drain current of 290 mA/mm and a peak extrinsic transconductance of 95 mS/mm. A

The hydrogen-terminated diamond surface has demonstrated unique potential in the development of high power and high frequency field effect transistors (FETs) [1]. Further exploration into the intrinsic performance limitations and device operation as

With nanotextured surfaces and interfaces increasingly being encountered in technological and biomedical applications, there is a need for a better understanding of frictional properties involving such surfaces. Here we report friction measurements o

Nucleation is the rate-determining step in the initial stages of most chemical vapour deposition processes. In order to achieve uniform deposition of diamond thin films it is necessary to seed non-diamond substrates. Here we discuss a simple electros

A comprehensive study of microwave (MW) activated CH4/H2/Ar plasmas used for diamond chemical vapor deposition is reported, focusing particularly on the effects of gross variations in the H2/Ar ratio in the input gas mixture (from H2/Ar mole fraction
