    • Comparison of geometric and drive-induced nonlinearities in doubly clamped, thermoelastic nanoelectromechanical systems 

      Hanay, Mehmet Selim (TÜBİTAK, 2019-06)
      The performance of resonant sensors based on nanoelectromechanical systems depends critically on the maximum amplitude of oscillation reached in the linear regime. The maximum linear amplitude is determined by nonlinear ...
    • Full electrostatic control of nanomechanical buckling 

      Erbil, Selçuk Oğuz; Hatipoğlu, Utku; Yanık, C.; Ghavami, Mahyar; Arı, Atakan B.; Yüksel, Mert; Hanay, Mehmet Selim (American Physical Society, 2020)
      Buckling of mechanical structures results in bistable states with spatial separation, a feature desirable for sensing, shape configuration, and mechanical computation. Although different approaches have been developed to ...
    • 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 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, 2021-01-13)
      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 ...
    • Nonlinear nanomechanical mass spectrometry at the single-nanoparticle level 

      Yüksel, Mert; Orhan, Ezgi; Yanık, C.; Arı, Atakan B.; Demir, A.; Hanay, Mehmet Selim (American Chemical Society, 2019)
      Nanoelectromechanical systems (NEMS) have emerged as a promising technology for performing the mass spectrometry of large biomolecules and nanoparticles. As nanoscale objects land on NEMS sensors one by one, they induce ...
    • Observation of coupled mechanical resonance modes within suspended 3D nanowire arrays 

      Kılınç, Y.; Karakan, M. Çağatay; Leblebici, Y.; Hanay, Mehmet Selim; Alaca, B. E. (Royal Society of Chemistry, 2020)
      Complex yet compact nanoscale mechanisms have largely been absent due to the rather limited availability of components and integration techniques. Especially missing have been efficient interconnects with adjustable ...
    • Optimization of piezoresistive motion detection for ambient NEMS applications 

      Ti, C.; Arı, A.; Orhan, E.; Gonzalez, M.; Yanık, C.; Kaya, İ. İ.; Hanay, Mehmet Selim; Ekinci, K. L. (Institute of Electrical and Electronics Engineers, 2020)
      Electrical readout of nanomechanical motion in ambient pressure and temperature imposes an important challenge for emerging applications of nanoelectromechanical systems (NEMS). Here, we optimize a metallic piezoresistive ...
