Description :
The impact of boron doping level of nanocrystalline diamond (NCD) films on the character of cell growth (i.e., adhesion, proliferation and differentiation) is presented. Intrinsic and boron-doped NCD films were grown on Si/SiO2 substrates by microwave plasma CVD process. The boron-doped samples were...

Description :
The need for more advanced, accurate and lower cost sensor platforms is constantly growing. However, for certain applications the already existing sensing systems based on biological recognition elements have sometimes restrictions, which limit their use. As a result, sensors with synthetic recognit...

Description :
Current experimental microwave plasma enhanced chemical vapour deposition (MW PECVD) concepts for diamond thin films do not allow scaling up towards large areas, which is essential for microelectronic industries. Also, current growth temperatures are rather high and not compatible with processing te...

Effects of hole and electron trapping on organic field-effect transistor transfer characteristic
Description :
Routine organic field-effect transistor measurements are performed at negative and positive gate voltages leading to the occurrence of both hole and electron trapping. Despite this fact, the big majority of studies have focused either on hole trapping or on electron trapping but not on both at the s...

Description :
The high prevalence of cardiovascular diseases (CVD) demands a reliable and sensitive risk assessment technique. In order to develop a fast and label-free immunosensor for C-reactive protein (CRP), a risk factor for this condition, anti-CRP antibodies were physically adsorbed to the hydrogen (H)-ter...

Description :
Thermionic electron emitters are a crucial component in applications ranging from high power telecommunication, electron guns, space thrusters and direct thermal to electrical energy converters. One key characteristic of diamond based electron sources is the negative electron affinity (NEA) properti...

Description :
The early growth stages of chemical vapor deposition(CVD) diamond on a sol-gel TiO2 with buried ultra dispersed diamond seeds(UDD)have been studied. In order to investigate the diamond growth mechanism and understand the role of the TiO2 layer in the growth process, high resolution transmission elec...

Description :
Serotonin is an important signaling molecule in the human body. The detection of serotonin is commonly performed by high performance liquid chromatography (HPLC), which is costly and time consuming due to extensive sample preparation. We will show that these problems can be overcome by using molecul...

Description :
Phase pure cubic BoronNitride (c-BN) films were epitaxially grown on (001) Diamond substrates at 900 degrees C and analyzed for purity by taking X-ray Photoelectron Spectroscopy (XPS) as well as Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) depth profiles. No metallic impurities could be...

Description :
Thin aluminium nitride (AIN) films of different thickness are deposited by DC-pulsed magnetron sputtering under identical conditions on sapphire (0001) and silicon (100) substrates. An investigation of the residual stress, morphology and structural properties is carried out. The thickness of the fil...
