In order to present your research at the Forum, send a title, author list, affiliations, and an abstract to Ze'ev Abrams by FRIDAY, APRIL 17, 2009 Extended Deadline!. Please do not exceed 250 words. For more information, please visit the 2009 Berkeley Nanotechnology Forum page. 
Congratulations to the following scholars for winning prizes in the Poster Session of the 2009 Berkeley Nanotechnology Forum! 1st Place - $1000 Graphene at the Edge: Stability and Dynamics Çağlar Girit (UC Berkeley) Although the physics of materials at surfaces and edges has been extensively studied, the movement of individual atoms at an isolated edge has not been directly observed in real time. Here we present a movie of the dynamics of carbon atoms at the edge of a hole in a suspended, single atomic layer of graphene taken with a transmission electron aberration-corrected microscope capable of simultaneous atomic spatial resolution and one second temporal resolution. The rearrangement of bonds and beam-induced ejection of carbon atoms is recorded as the hole grows. We investigate the mechanism of edge reconstruction and demonstrate the stability of the “zigzag” edge configuration. This study of an ideal low-dimensional interface, a hole in graphene, exhibits the complex behavior of atoms at a boundary. 2nd Place - $700 Inorganic Nanowire Arrays and Hybrid Nanomaterials for Renewable Solar Energy Applications Ilan Jen-La Plante (UC Berkeley) The alarming combination of rapidly increasing global energy consumption and the impact of fossil fuel driven climate change has led to great interest in the development of renewable energy sources. In this poster, we present novel syntheses of inorganic and hybrid nanomaterials with potential applications for renewable energy generation. For solar energy devices, including solar photovoltaic cells and photo-electrochemical cells, the incorporation of ordered nanowire arrays may lead to high efficiencies due to better carrier mobility and efficient exciton formation in the inorganic nanowire layer. Here we show the synthesis of substrate bound metal chalcogenide (Cu2S, CdSe, CdS, PbSe, PbS) nanowire arrays as an ideal material system for stable and efficient hybrid inorganic-organic solar cells. Furthermore, multi-material hybrid nanomaterials, which include a combination of two different material types, can lead to novel functionalities that are independent of the individual components and may be tailored to fit specific application requirements. We demonstrate the ability to form hybrid nanostructures from inorganic nanowire materials. This includes core/shell heterostructures where an inorganic core nanowire is encapsulated in a secondary material (CdSe@CdZnS, CdSe@ZnTe) as well as multi-material structures of metal-semiconductor nanowires (CdX-Au, CdX-Pt, CdX-Ru; where X = Se, S). This combination of catalytically active metals with semiconductor nanowires may show promise as good materials for renewable energy conversion, specifically photo-electrochemical water splitting. 3rd Place - $300 Dielectric Optical Cloak Jason Valentine (UC Berkeley) Recent theories including transformation optics (TO) and conformal mapping have proposed that cloaking devices are in principle possible, given the availability of the appropriate medium. The advent of metamaterials has provided such a medium where the electromagnetic material properties can be tailored at will, enabling precise control over the spatial variation in the material response. Utilizing metamaterials the first cloaks have recently been demonstrated at microwave frequencies, however, so far there is a lack of an experimental demonstration at optical frequencies. We report the first experimental realization of a dielectric optical cloak utilizing a form of cloaking deemed “carpet cloaking”. The cloak is designed using quasi-conformal mapping to conceal an object that is placed under a curved reflecting surface which imitates the reflection of a flat surface. Our cloak consists only of isotropic dielectric materials which enables broadband and low-loss invisibility at a wavelength range of 1400-1800 nm. People's Choice Award - $500 Spontaneous Formation of Two Dimensional Crystalline Sheet from Periodic Amphiphilic Peptoid Polymers Amanda Marciel (UC Berkeley) Biological self-assembly and biomolecular recognition continue to inspire novel approaches for the fabrication of bioanalytical, electrical and optical devices, via the organization of building blocks into hierarchical structures. Self-assembling peptide and protein systems have been used to make wires, fibers, tubes, vesicles and other structures that are highly ordered on the nanometer scale. The ability to fabricate such materials would allow the miniaturization of components of bioanalytical devices, electrochemical devices (such as batteries, fuel cells and supercapacitors), membranes for filtration and separation, surface coatings with chemically defined surfaces and biosensors. Recent discoveries have lead to the development of unique self-assembled crystalline nanostructures derived from biologically-inspired polymer materials (peptoids) that demonstrate potential for such applications. Peptoids are a class of non-natural biopolymers based on oligo-N-substituted glycine backbones, designed to mimic peptides and proteins. They are efficiently assembled via automated solid-phase synthesis from hundreds of chemically diverse building blocks allowing the rapid generation of huge combinatorial libraries. This provides an ideal platform to discover nanostructured material capable of protein-like molecular recognition and function. We have designed two complimentary charged peptoid molecules consisting of alternating apolar and polar residues. When mixed in aqueous solution the peptoids self-assemble into a two-dimensional sheet structure. Characterization of the sheet structure by atomic force microscopy, fluorescence microscopy, transmission electron microscopy, differential scanning calorimetry and x-ray diffraction have elucidated the atomic details of the crystalline structure revealing a sheet thickness of just 3 nm, as well as their kinetics of formation and thermodynamic stabilities.
