Surface waves and atomic force microscope probe-particle near-field coupling: discrete dipole approximation with surface interaction
Loke, Vincent L. Y.; Mengüç, Mustafa Pınar (Optics InfoBase, 2010-10)Evanescent waves on a surface form due to the collective motion of charges within the medium. They do not carry any energy away from the surface and decay exponentially as a function of the distance. However, if there is ... -
Surfactant mediated slurry formulations for Ge CMP applications
Başım, Gül Bahar; Karagöz, Ayşe; Chen, L.; Vakarelski, I. (Cambridge University Press, 2013)In this study, slurry formulations in the presence of self-assembled surfactant structures were investigated for Ge/SiO2 CMP applications in the absence and presence of oxidizers. Both anionic (sodium dodecyl sulfate-SDS) ... -
Thermal enhancement of an LED light engine for automotive exterior lighting with advanced heat spreader technology
Uras, Umut Zeynep; Tamdoğan, Enes; Arık, Mehmet (ASME, 2016)In recent years, light emitting diodes (LEDs) have become an attractive technology for general and automotive illumination systems. LEDs have been preferable for automobile lighting due to its numerous advantages such as ... -
Thermal performance of a light emitting diode light engine for a multipurpose automotive exterior lighting system with competing board technologies
Uras, Umut Zeynep; Arık, Mehmet; Tamdoğan, Enes (ASME, 2017-06-12)In recent years, light emitting diodes (LEDs) have become an attractive technology for general and automotive illumination systems replacing old-fashioned incandescent and halogen systems. LEDs are preferable for automobile ... -
Topology optimization of an anti roll bar of a heavy commercial truck for vehicle dynamics and durability
Yenilmez, Ece; Yaşar, Ali; Şendur, Polat (The American Society of Mechanical Engineers, 2019)Meeting the stringent requirements on fuel economy and emissions is still a challenge for automotive original equipment manufacturers (OEMs). In this study, we consider the light weighting opportunities of a heavy commercial ... -
Topology optimization of constrained and unconstrained damping layers
Mansouri, Deniz; Şendur, Polat (Canadian Acoustical Association, 2019)Damping is an effective way of suppressing mechanical vibrations. Passive constrained and unconstrained layer damping patches are often used in the industry as damping solution for vibrations and acoustics problems. In ... -
Understanding selectivity on Germanium/SiO2 chemical mechanical planarization through design of experiments
Karagöz, Ayşe; Mal, J.; Başım, Gül Bahar (Cambridge University Press, 2015)The continuous trend of achieving more complex microelectronics with smaller nodes yet larger wafer sizes in microelectronics manufacturing lead to aggressive development requirements for chemical mechanical planarization ... -
Workability characteristics and mechanical behavior modeling of severely deformed pure titanium at high temperatures
Sajadifar, Seyed Vahid; Yapıcı, Güney Güven (Elsevier, 2014-01)In the present study, compression tests were performed at temperatures of 600–900 °C and at strain rates of 0.001–0.1 s−1 to study the deformation and workability characteristics of commercially pure titanium after severe ...
