This Week's Seminar
11:00 am - 12:30 pm 521 Cory Hall MING LIU, Scalable and Integrated Nano Manufacturing (SINAM) Center, ME, UCB Nano-scale plasmonic motors driven by light AbstractThe ability to provide rotational force in nano-meter scale opens up a new realm of applications in physics, biology and chemistry, ranging from DNA unfolding and sequencing, to active Nano-Electro-Mechanical Systems (NEMS). In this talk, I will show you that a nano-scale plasmonic structure generating a significantly large rotational force when illuminated with linearly-polarized light. We find that a metallic particle with size of 1/10 of the wavelength is capable of rotating a silica microdisk, 4,000 times larger in volume. Furthermore, we control the rotation velocity and direction by merely varying the wavelength of the incident light, thereby inducing different plasmonic modes which possess different torque directions. At the end of the talk, I would like to talk about the latest results we get on a graphene-based optoelectrical device. Bio |
