Optical manipulation of plasmonic nanoparticles provides opportunities for fundamental and technical innovation in nanophotonics. Optical heating arising from the photon-to-phonon conversion is considered as an intrinsic loss in metal nanoparticles, which limits their applications. We show here that this drawback can be turned into an advantage, by developing an extremely low-power optical tweezing technique, termed opto-thermoelectric nanotweezers. By optically heating a thermoplasmonic substrate, a light-directed thermoelectric field can be generated due to spatial separation of dissolved ions within the heating laser spot, which allows us to manipulate metal nanoparticles of a wide range of materials, sizes and shapes with single-particle resolution. In combination with dark-field optical imaging, nanoparticles can be selectively trapped and their spectroscopic response can be resolved in situ. With its simple optics, versatile low-power operation, applicability to diverse nanoparticles and tunable working wavelength, opto-thermoelectric nanotweezers will become a powerful tool in colloid science and nanotechnology.

Plasmonic resonances in sub-terahertz fishnet metamaterial based on complementary hexagonal resonator
Yuksek, Yahya; Demir, S. Mahircan; Sabah, Cumali (Elsevier BV, 2019-01-01)
Exploration of the perfect combination between metamaterials (MTMs) and plasmonics has paved the way of the new innovations in electromagnetic and communication engineering, especially in sub-THz spectroscopy. In order to contribute to such developments, plasmonic resonances in sub-THz fishnet MTM on the basis of complementary hexagonal resonator structure is investigated in this paper. The design, in which method of removing hexagonal structure is applied, has been performed based on finite simulation tech...
Sensory applications of resonator based metamaterial absorber
BAKIR, MEHMET; KARAASLAN, MUHARREM; AKGÖL, OĞUZHAN; ALTINTAŞ, OLCAY; ÜNAL, EMİN; Sabah, C. (Elsevier BV, 2018-01-01)
Metamaterials are attractive media for scientific society for their potential multi-functional and a wide range of applications due to their unusual electromagnetic properties. In this paper, we present several important applications including pressure, density and volumetric moisture sensing based on rectangular split ring structure with a strip line. These applications are carried out experimentally and numerically. Since the sensing ability is mostly connected with the resonance frequencies, we have care...
Nonlinear free vibrations of curved double walled carbon nanotubes using differential quadrature method
Ciğeroğlu, Ender (Elsevier BV, 2014-11-01)
Nonlinear free vibration analysis of curved double-walled carbon nanotubes (DWNTs) embedded in an elastic medium is studied in this study. Nonlinearities considered are due to large deflection of carbon nanotubes (geometric nonlinearity) and nonlinear interlayer van der Waals forces between inner and outer tubes. The differential quadrature method (DQM) is utilized to discretize the partial differential equations of motion in spatial domain, which resulted in a nonlinear set of algebraic equations of motion...
Electronic structure of carbon nanotubes: AM1-RHF calculations
Erkoç, Şakir; Turker, L (Elsevier BV, 1999-07-01)
We have investigated the electronic structure of optimized open-ended single-wall carbon nanotubes with armchair and zigzag geometries. The calculations were performed using AM1-RHF semiempirical molecular orbital method. It has been found that the density of states of the zigzag model is more sensitive to the tube size than that of the armchair model.
Engineering nonlinear response of nanomaterials using Fano resonances
Turkpence, Deniz; Akguc, Gursoy B.; Bek, Alpan; Taşgın, Mehmet Emre (IOP Publishing, 2014-10-01)
We show that nonlinear optical processes of nanoparticles can be controlled by the presence of interactions with a molecule or a quantum dot. By choosing the appropriate level spacing for the quantum emitter, one can either suppress or enhance the nonlinear frequency conversion. We reveal the underlying mechanism for this effect, which is already observed in recent experiments: (i) suppression occurs simply because transparency induced by Fano resonance does not allow an excitation at the converted frequenc...
