Shape-Directed Binary Assembly of Anisotropic Nanoplates: A Nanocrystal Puzzle with Shape-Complementary Building Blocks

We present the binary self-assembly of two anisotropic nanoplate building blocks mediated by shape complementarity. We use rhombic GdF3 and tripodal Gd2O3 nanoplates as building blocks in which the size and shape are designed to be optimal for complementary ... [Published Nano Letters - 19 hours ago]

Surface-Sensitive Two-Dimensional Magneto-Fingerprint in Mesoscopic Bi2Se3 Channels

Periodic Aharonov–Bohm and Altshuler–Aronov–Spivak oscillations have traditionally been observed in lateral transport through patterned mesoscopic loops of diffusive conductors. However, our studies of perpendicular-to-plane magnetotransport in straight-channel, ... [Published Nano Letters - 21 hours ago]

Theory of Coherent Nucleation in Phase-Separating Nanoparticles

The basic physics of nucleation in solid single-crystal nanoparticles is revealed by a phase-field theory that includes surface energy, chemical reactions, and coherency strain. In contrast to binary fluids, which form arbitrary contact angles at surfaces, ... [Published Nano Letters - 21 hours ago]

High Efficiency Solid-State Sensitized Solar Cell-Based on Submicrometer Rutile TiO2 Nanorod and CH3NH3PbI3 Perovskite Sensitizer

We report a highly efficient solar cell based on a submicrometer (0.6 μm) rutile TiO2 nanorod sensitized with CH3NH3PbI3 perovskite nanodots. Rutile nanorods were grown hydrothermally and their lengths were varied through the control of the reaction time. ... [Published Nano Letters - May 17 2013]

Control and Near-Field Detection of Surface Plasmon Interference Patterns

The tailoring of electromagnetic near-field properties is the central task in the field of nanophotonics. In addition to 2D optics for optical nanocircuits, confined and enhanced electric fields are utilized in detection and sensing, photovoltaics, spatially ... [Published Nano Letters - May 16 2013]

Seebeck Coefficient of Nanowires Interconnected into Large Area Networks

We measured the macroscopic Seebeck coefficient of silicon nanowires (SiNWs), organized in a highly interconnected networks on large areas (order of mm2). The fabricated networks are very reliable with respect to random nanowire failure and are electrically ... [Published Nano Letters - May 16 2013]
