    • Atomic force microscopy: Methods and applications 

      Baykara, Mehmet Z.; Schwarz, U. D. (Elsevier, 2017)
      This chapter provides an overview of atomic force microscopy, covering the fundamental aspects of the associated instrumentation and methodology as well as representative results from the literature highlighting a variety ...

    • Design, fabrication, and applications of electrostatically buckled nanomechanical systems 

      Erbil, Selçuk Oğuz (Bilkent University, 2018-08)
      Buckling is an important resource for memory and sensing applications at the micro- and nano-scale. Although di erent approaches have been developed to access buckling, such as the use of pre-stressed beams or thermal ...

    • Design, fabrication, and applications of multi-mode nanoelectromechanical systems 

      Arı, Atakan Bekir (Bilkent University, 2017-07)
      Miniaturization of systems allowed wide spread consumer use of microelectronics, integrated circuits and MEMS based sensors. Thanks to the advancement in microfabrication methods, it is possible to build structures with ...

    • Direct measurement of interatomic force gradients using an ultra-low-amplitude atomic force microscope 

      Hoffmann, P. M.; Oral, A.; Grimble, R. A.; Özer, H. Ö.; Jeffery, S.; Pethica, J. B. (The Royal Society Publishing, 2001)
      Interatomic force gradients between a W tip and a 7 × 7 reconstructed Si(111) surface were measured using an off-resonance, ultra-low-amplitude atomic force microscope (AFM) technique. The amplitudes used were less than 1 ...

    • Linear measurements of nanomechanical phenomena using small-amplitude AFM 

      Hoffmann, P. M.; Patil, S.; Matei, G.; Tanülkü, A.; Grimble, R.; Özer, Ö.; Jeffery, S.; Oral, Ahmet; Pethica, J. (Materials Research Society, 2004)
      Dynamic Atomic Force Microscopy (AFM) is typically performed at amplitudes that are quite large compared to the measured interaction range. This complicates the data interpretation as measurements become highly non-linear. ...

    • Nanomechanical measurement of the Brownian force noise in a viscous liquid 

      Arı, A. B.; Hanay, Mehmet Selim; Paul, M. R.; Ekinci, K. L. (American Chemical Society, 2020)
      We study the frequency spectrum of the thermal force giving rise to Brownian motion of a nanomechanical beam resonator in a viscous liquid. In the first set of experiments, we measure the power spectral density (PSD) of ...

    • Nanomechanical motion transducers for miniaturized mechanical systems 

      Kouh, T.; Hanay, M. S.; Ekinci, K. L. (MDPI AG, 2017)
      Reliable operation of a miniaturized mechanical system requires that nanomechanical motion be transduced into electrical signals (and vice versa) with high fidelity and in a robust manner. Progress in transducer technologies ...

    • Nanomechanics using an ultra-small amplitude AFM 

      Hoffmann, P. M.; Jeffery, S.; Oral, Ahmet; Grimble, R. A.; Özer, H. Özgür; Pethica, J. B. (Cambridge University Press, 2001)
      A new type of AFM is presented which allows for direct measurements of nanomechanical properties in ultra-high vacuum and liquid environments. The AFM is also capable to atomic-scale imaging of force gradients. This is ...
