    • Enhanced higher-harmonic imaging in tapping-mode atomic force microscopy 

      Balantekin, M.; Atalar, Abdullah (AIP, 2005)
      Higher-harmonics generation in a tapping-mode atomic force microscope is a consequence of the nonlinear tip-sample interaction force. The higher harmonics contain important information about the materials’ nanomechanical ...
    • Fabrication and characterization of microelectromechanical resonators 

      Özer, Sevil (Bilkent University, 2006)
      Micromachined mechanical resonators are of considerable interest because of their many important scienti c and technological applications. They can be used as a components of radio-frequency lters in communication ...
    • Grating loaded integrated optical cantilevers 

      Karademir, Ertuğrul (Bilkent University, 2010)
      Cantilever beams are the most important parts of standard scanning probe microscopy. In this work, an integrated optical approach to sense the deflection of a cantilever beam is suggested and realized. A grating coupler ...
    • High-resolution imaging of elastic properties using harmonic cantilevers 

      Sahin, O.; Yaralioglu, G.; Grow, R.; Zappe, S. F.; Atalar, Abdullah; Quate, C.; Solgaard, O. (Elsevier, 2004)
      We present a micromachined scanning probe cantilever, in which a specific higher-order flexural mode is designed to be resonant at an exact integer multiple of the fundamental resonance frequency. We have fabricated such ...
    • Investigation of lateral forces in dynamic mode using combined AFM/STM 

      Atabak, Mehrdad (Bilkent University, 2007)
      In this Ph.D. work, we constructed a ¯ber optic interferometer based non-contact Atomic Force Microscope (nc-AFM) combined with Scanning Tunneling Micro- scope(STM) to study lateral force interactions on Si(111)-(77) ...
    • Microcantilever based disposable viscosity sensor for serum and blood plasma measurements 

      Cakmak O.; Elbuken, C.; Ermek, E.; Mostafazadeh, A.; Baris I.; Erdem Alaca, B.; Kavakli I.H.; Urey H. (2013)
      This paper proposes a novel method for measuring blood plasma and serum viscosity with a microcantilever-based MEMS sensor. MEMS cantilevers are made of electroplated nickel and actuated remotely with magnetic field using ...
