  • Development of high-stable contact systems to gallium nitride microwave diodes 
    Belyaev, A.E.; Boltovets, N.S.; Ivanov, V.N.; Kapitanchuk, L.M.; Kladko, V.P.; Konakova, R.V.; Kudryk, Ya.Ya.; Kuchuk, A.V.; Lytvyn, O.S.; Milenin, V.V.; Sheremet, V.N.; Sveshnikov, Yu.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2007)
    High-stable heat-resistant low-resistance contact systems with diffusion barriers involving quasi-amorphous TiBx layers are suggested and studied. We have performed the structural and morphological investigations along ...
  • Investigation of resistance formation mechanisms for contacts to n-AlN and n-GaN with a high dislocation density 
    Sachenko, A.V.; Belyaev, A.E.; Boltovets, N.S.; Zhilyaev, Yu.V.; Kapitanchuk, L.M.; Klad’ko, V.P.; Konakova, R.V.; Kudryk, Ya.Ya.; Kuchuk, A.V.; Naumov, A.V.; Panteleev, V.V.; Sheremet, V.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2012)
    We studied temperature dependences of the resistivity, Pc(T) , of Pd-Ti-Pd-Au ohmic contacts to wide-gap semiconductors n - GaN and n - AlN with a high dislocation density. BothPc(T) curves have portions of exponential ...
  • Mechanism of current flow and temperature dependence of contact resistivity in Au-Pd-Ti-Pd-n⁺ -GaN ohmic contacts 
    Sachenko, A.V.; Belyaev, A.E.; Boltovets, N.S.; Kapitanchuk, L.M.; Klad’ko, V.P.; Konakova, R.V.; Kuchuk, A.V.; Korostinskay, T.V.; Pilipchuk, A.S.; Sheremet, V.N.; Mazur, Yu.I.; Ware, M.E.; Salamo, G.J. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2013)
    We present the results of structural and morphological investigations of interactions between phases in the layers of Au-Pd-Ti-Pd-n⁺-GaN contact metallization that appear at rapid thermal annealing (RTA). It is shown that ...
  • Ohmic contacts to Hall sensors based on n-InSb-GaAs(i) heterostructures 
    Boltovets, N.S.; Konakova, R.V.; Kudryk, Ya.Ya.; Milenin, V.V.; Mitin, V.F.; Mitin, E.V.; Lytvyn, O.S.; Kapitanchuk, L.M. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2006)
    We consider ohmic contacts to the n-InSb epitaxial layers grown on a semi-insulating GaAs substrate. The ohmic contacts are formed through titanium metallization with subsequent gilding. Using the structural (AFM and XRD) ...
  • Role of dislocations in formation of ohmic contacts to heavily doped n-Si 
    Belyaev, A.E.; Pilipenko, V.A.; Anischik, V.M.; Petlitskaya, T.V.; Klad’ko, V.P.; Konakova, R.V.; Boltovets, N.S.; Korostinskaya, T.V.; Kapitanchuk, L.M.; Kudryk, Ya.Ya.; Vinogradov, A.O.; Sheremet, V.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2013)
    We present experimental results concerning a high density of structural defects (in particular, dislocations) in the near-contact region of heavily doped n-silicon. They appear in the course of firing Au Pd Ti Pd -Si n ...
  • The features of temperature dependence of contact resistivity of Au-Ti-Pd₂Si-p⁺ ₋Si ohmic contacts

    We consider the features of formation of Au-Ti-Pd ohmic contacts to p⁺₋Si. Metallization was made by vacuum thermal sputtering of Pd, Ti and Au films onto the Si substrate heated up to 330 °С. It is shown that the contact ...
  • Thermoexfoliated graphite — transitional metal nanocomposites 
    Len, T.A.; Matzui, L.Yu.; Babich, N.G.; Kopan, V.S.; Kapitanchuk, L.M. (Functional Materials, 2004)
    Composite materials (CM) have been obtained by chemical deposition of metal on graphite surface. It has been shown that TEG-nanoscaled transition metal CM can be prepared both by long-term salt decomposition on TEG surface ...
