Fourier transform photocurrent spectroscopy of dopants and defects in CVD diamond

Author(s) : Vanecek, M , Kravets, R , Poruba, A , Rosa, J , NESLADEK, Milos , Koizumi, S
Description : Fourier-transform photocurrent spectroscopy (FrPS) was used as a very sensitive spectroscopic method to detect shallow and deep impurities (dopants) in CVD diamond layers. Detailed study of experimental conditions (temperature, frequency, electric field, bias light, surface conditions) was performed...

ESR and photo-ESR study of defects in CVD diamond

Author(s) : Iakoubovskii, K , Stesmans, A , NESLADEK, Milos , KNUYT, Gilbert
Description : Two hydrogen and two Si-related defect centers were detected and characterized by electron spin resonance (ESR) in diamond films grown by chemical vapor deposition. Observation of hyperfine structure, combined with illumination and polishing treatments, suggests that the KUL2 and KUL9 ESR centers or...

CVD diamonds as thermoluminescent detectors for medical applications

Author(s) : Marczewska, B , Olko, P , NESLADEK, Milos , Waligorski, MPR , Kerremans, Y
Description : Diamond is believed to be a promising material for medical dosimetry due to its tissue equivalence, mechanical and radiation hardness, and lack of solubility in water or in disinfecting agents. A number of diamond samples, obtained tinder different growth conditions at Limburg University, using the ...

Superconductivity and low-dimensional electrical transport in nanocrystalline diamond

Author(s) : NESLADEK, Milos , Mares, J.J. , Hubik, P.
Description : The aim of this paper is to summarise recent progress in the growth and doping of small-grain-sized chemical vapor deposition (CVD) diamond, often called nanocrystalline diamond. Nanodiamond thin films are interesting for many industrial applications as mechanically resilient layers or optical or bi...

Studies on the application of CVD diamonds as active detectors of ionising radiation

Author(s) : Marczewska, B , Nowak, T , Olko, P , NESLADEK, Milos , Waligorski, MPR
Description : Due to its tissue-equivalence, radiation hardness, resistivity to chemicals and thermal stability, diamond is becoming an interesting material for developing dosimeters of ionising radiation. Several types of CVD diamonds grown at the Institute for Materials Research at the Limburg University, Belgi...

EPR study of preferential orientation of crystallites in N-doped high quality CVD diamond

Author(s) : Nokhrin, S , Rosa, J , Vanecek, M , Badalyan, AG , NESLADEK, Milos
Description : The directions of preferential growth of free-standing optical-quality CVD diamond wafers have been investigated with the help of electron paramagnetic resonance (EPR). EPR signals of the well-known P1 centre (substitutional nitrogen) have been used as a probe. A computer simulation of EPR spectra o...

Electronic states of phosphorus in diamond

Author(s) : Gheeraert, E , Koizumi, S , Teraji, T , Kanda, H , NESLADEK, Milos
Description : A set of rt-type diamond thin films was investigated by infra-red absorption spectroscopy. The films were grown by CVD on {111} synthetic diamond, and phosphorus-doped using [P]/[C] = 100-5000 ppm of phosphine in the gas phase during growth. The phosphorus concentration in the films ranged from arou...

Photothermal deflection mapping of variations in the optical absorption in IR windows

Author(s) : REMES, Zdenek , NESLADEK, Milos , MEYKENS, Kristien , Pickles, CSJ , Sussman, RS
Description : We used the photothermal deflection (PTD) technique working in a collinear mode to measure optical PTD maps of polished ZnSe, CVD and natural type IIa diamond optical windows at the CO2 laser wavelength (10.6 mu m). This technique is sensitive to inhomogeneous absorption. The variations in PTD signa...

Electronic states of boron and phosphorus in diamond

Author(s) : Gheeraert, E , Kozumi, S , Teraji, T , Kanda, H , NESLADEK, Milos
Description : The electronic states of boron and phosphorus in diamond have been studied by infrared absorption and photo-thermal ionisation spectroscopies. High quality boron doped synthetic diamond (p-type conductive) and phosphorus-doped CVD diamond film (n-type conductive) were used for this study. In the cas...

Photoluminescence excitation and quenching spectra in CVD diamond films

Author(s) : Iakoubovskii, K , Adriaenssens, GJ , NESLADEK, Milos , STALS, Lambert
Description : Photoluminescence excitation and quenching spectroscopy techniques were applied to the red band, and the 1.68, 1.945 and 2.156 eV lines in chemical vapour deposition diamond films. Ground state positions for the 1.68, 1.945 and 2.156 eV centers are found as E-C -2.1, -2.0 and -2.8 eV, respectively. ...
