  • Arshak, Arousian; Zleetni, S.M.; Arshak, Khalil; Harris, John A. (IEEE Computer Society, 2001)
    The dosimetry properties of thermally evaporated Copper Phthalocyanine (CuPc) thin films were investigated. The conduction mechanism of the asdeposited films was found to be space-charge-limited and their relative ...
  • Arshak, Khalil; Nicolson M; Arshak, Arousian; Moore, Edward G.; Gaidan, Ibrahim; Cunniffe, Colm (IEEE Computer Society, 2006)
    Investigations have been carried out on the role of the binder in screen printed Fe2O3/ZnO thick film sensors for gas and vapour analysis. These sensors were prepared by mixing a polymer binder and carbon black with a ...
  • Arshak, Khalil; Mihov, Miroslav; Arshak, Arousian; McDonagh, Declan; Sutton, D (IEEE Computer Society, 2004)
    Focused Ion Beam (FIB) lithography has significant advantages over the electron beam counterpart in terms of resist sensitivity, backscattering and proximity effects. Applying the Top Surface Imaging (TSI) principal to ...
  • Arshak, Khalil; Korostynska, Olga; Jafer, Essa; Arshak, Arousian; Morris, Deirdre; Gill, Edric I. (IEEE Computer Society, 2006)
    A novel cost-effective real-time gamma radiation monitoring system based on metal oxide thick films was designed and tested. The changes in capacitances of ZnO and SnO2 thick film capacitors with interdigitated ...
  • Arshak, Khalil; Morris, Deirdre; Arshak, Arousian; Korostynska, Olga; Kaneswaran, Kelly (IEEE Computer Society, 2002)
    This paper examines the sensitivity of polyvinylidene fluoride (PVDF) and polyvinyl butyral (PVB) capacitors to pressures ranging from 0 – 100 kPa. The capacitors were formed by screenprinting onto flexible substrates and ...
  • Arshak, Khalil; Gill, Edric I.; Arshak, Arousian; Korostynska, Olga (IEEE Computer Society, 2007)
    Due to the increasing demand for accurate, reliable and highly sensitive pH sensors, research is ongoing to find new materials and methods to achieve this goal. An approach that shows promise in the pH-sensing field is the ...
  • Arshak, Khalil; Jafer, Essa; Arshak, Arousian; Waldron, David (IEEE Computer Society, 2006)
    In this paper, a miniaturized, low power, bidirectional wireless communication system has been developed to be used for in vivo pressure monitoring. The system prototype consists of miniature FSK transceiver integrated ...
  • Arshak, Khalil; Mihov, Miroslav; Arshak, Arousian; McDonagh, Declan; Pomeroy, Michael J. (IEEE Computer Society, 2001)
    The positive resist image by dry etching (PRIME) process is a high resolution lithography system incorporating electron beam exposure, silylation and dry development. The process steps in PRIME with Shipley SPRSOSA ...
  • Arshak, Arousian; Arshak, Khalil; McDonagh, Declan; Mathur, B.P. (IEEE Computer Society, 1995)
    This paper describes the modelling and simulation of two resolution enhancement techniques in lithography ; 1) phase shift mask (PSM) technology and 2) top surface imaging (TSI) with silylation and dry ...
  • Arshak, Khalil; Gilmartin, Stephen L.; Arshak, Arousian; Collins, Damien; Korostynska, Olga (IEEE Computer Society, 2005)
    The 2-step negative resist image by dry etching (2-step NERIME) focused ion beam (FIB) top surface imaging (TSI) process has been previously reported as an excellent technique for patterning nanometer scale features ...
  • Gill, Edric; Arshak, Arousian; Arshak, Khalil; Korostynska, Olga (MDPI, 2007)
    This paper reports on the results from the investigation into the pH sensitivity of novel PANI/PVB/PS3 composite films. The conductimetric sensing mode was chosen as it is one of the most promising alternatives to the ...
  • Arshak, Khalil; Korostynska, Olga; Arshak, Arousian; Morris, Deirdre (IEEE Computer Society, 2005)
    The electrical properties of screen-printed TiO2 based thick films were explored in terms of gamma radiation influence. Screen-printed pn-heterojunctions and resistors were exposed to γ- radiation from a 137Cs source ...
  • Korostynska, Olga; Arshak, Khalil; Gill, Edric; Arshak, Arousian (MDPI, 2007)
    This paper reviews current state-of-the-art methods of measuring pH levels that are based on polymer materials. These include polymer-coated fibre optic sensors, devices with electrodes modified with pH-sensitive polymers, ...
  • Arshak, Khalil; Arshak, Arousian; Mihov, Miroslav; McDonagh, Declan (IEEE Computer Society, 2002)
    In this paper, liquid-phase silylation process for Top Surface Imaging Lithography systems incorporated e-beam exposure has been experimentally investigated using FT-IR spectroscopy, UV spectroscopy, SIM spectrometry ...
  • Arshak, Khalil; Arshak, Arousian; Morris, Deirdre; Korostynska, Olga; Jafer, Essa (IEEE Computer Society, 2005)
    The ability to monitor pressure remotely is of particular importance in medical and environmental applications as it is less labour intensive, safer and offers peace of mind to the general public. To meet this demand, a ...
