This paper suggests epitaxy of silicon for emitter formation by high temperature CVD as an alternative to conventional processing for standard silicon wafer solar cells. Epitaxy could provide an alternative method to create an adjustable emitter shape at a short deposition time. Results of solar cells of phosphorous-doped epitaxial layers on p-type silicon(More)
Unimorph heterostructures based on piezoelectric aluminum nitride (AlN) and diamond thin films are highly desirable for applications in micro- and nanoelectromechanical systems. In this paper, we present a new approach to combine thin conductive boron-doped as well as insulating nanocrystalline diamond (NCD) with sputtered AlN films without the need for any(More)
Photonic active diamond nanoparticles attract increasing attention from a wide community for applications in drug delivery and monitoring experiments as they do not bleach or blink over extended periods of time. To be utilized, the size of these diamond nanoparticles needs to be around 4 nm. Cluster formation is therefore the major problem. In this paper we(More)
Silicon carbide (SiC) films have been used frequently for high-frequency and powder devices but have seldom been applied as the electrode material. In this paper, we have investigated the electrochemical properties of the nanocrystalline 3C-SiC film in detail. A film with grain sizes of 5 to 20 nm shows a surface roughness of about 30 nm. The resistivity of(More)
Tunable micro lenses based on boron-doped nanocrystalline diamond and aluminum nitride (AlN) thin films are investigated. It is demonstrated that such a material combination is advantageous for the fabrication of highly transparent, mechanically stable optical components capable to operate at high actuation frequencies. In addition, it is shown that(More)
Quantitative analysis of X-ray absorption and dichroism data requires knowledge of the beamline photon flux during the measurements. We show that thin conductive (B-doped) diamond thin films can be an alternative to the widely used gold meshes for monitoring the beam intensity of soft X-ray beamlines in situ. Limited by the carbon extended x-ray absorption(More)
This work considers the challenges and technical solutions concerning the deposition of thin films and processing of emerging vacuum microelectromechanical systems (MEMS) based on nanodiamond flexural beams. It is demonstrated that the add-on processing of MEMS chips allows for fabrication of functional nano-features such as nanoscale anode-cathode spacing(More)
Nanocrystalline diamond nanoelectrode arrays (NEAs) have been applied to investigate surface-sensitive adsorption phenomena at the diamond-liquid interface. The adsorption of neutral methyl viologen (MV(0) ) was used as a model system. The adsorption of MV(0) was examined on hydrogen- and oxygen-terminated surfaces. On the hydrogenated nanoelectrode(More)
Silicon carbide has been proved as a candidate for power and high-frequency devices. In this paper, we show the application of nanocrystalline 3C-SiC as an electrochemical electrode and its electrochemical functionalization for biosensing applications. SiC electrodes show a wider potential window and lower background current than glassy carbon electrodes.(More)
In this report, the fabrication of all-nanocrystalline diamond (NCD) nanoelectrode arrays (NEAs) by e-beam lithography as well as of all-diamond nanoelectrode ensembles (NEEs) using nanosphere lithography is presented. In this way, nanostructuring techniques are combined with the excellent properties of diamond that are desirable for electrochemical sensor(More)
