    • Ab initio temperature dependent studies of the homoepitaxial growth on Si(0 0 1) surface 

      Dağ, S.; Ciraci, S.; Kılıç, Ç.; Fong, C. Y. (2001)
      We performed ab initio zero temperature and finite temperature molecular dynamics calculations to investigate the homoepitaxial growth on the Si(0 0 1) surface. How do the deposited atoms (adatoms) form addimers and how ...
    • Anisotropy sensitivity of an acoustic lens with slit aperture 

      Atalar, Abdullah; Ishikawa, I.; Ogura, Y.; Tomita, K. (IEEE, 1993)
      A conventional spherical acoustic lens is modified by restricting its aperture in the form of a slit to provide directional sensitivity. The spacing between the two parallel absorbing sheets forming the slit is adjustable ...
    • New directional acoustic lens: V-groove lens 

      Bozkurt, A.; Yarahoglu, G.; Atalar, Abdullah; Koymen, H. (IEEE, 1993)
      A new directional acoustic lens is introduced. The geometry is very similar to the line-focus lens except the lens cavity, which is shaped as a groove with flat-bottom V cross section. The slanted planar edges of the groove ...
    • Phase-matched self-doubling optical parametric oscillator 

      Kartaloğlu, T.; Köprülü, K. G.; Aytür, O. (IEEE, Piscataway, NJ, United States, 1996)
      A new self-doubling optical parametric oscillator (OPO) uses a single nonlinear crystal for both parametric generation and frequency doubling. It is based on a KTiOPO4 (KTP) crystal pumped by a Ti:Sapphire laser operating ...
