Apr. 2010- Ding et al. report on the use of deoxyribonucleic acid (DNA) origami as a scaffold for the assembly of gold nanoparticles into a carefully organized structure to create, ideally, a device with a strongly enhanced plasmonic resonance.
First-principles theoretical analysis of sequential hydride dissociation on surfaces of silicon thin films
We report results from first-principles density functional theory calculations for the mechanism and activation barrier of sequential hydride dissociation on crystalline silicon surfaces and discuss their implications for the surface chemical composition of hydrogenated amorphous silicon (a-Si:H) thin films. We find that, in the presence of fivefold coordinated surface Si atoms, surface ...
A plasmonic molecule consisting of a radiative element coupled with a subradiant (dark) element is theoretically investigated. The plasmonic molecule shows electromagnetic response that closely resembles the electromagnetically induced transparency in an atomic system. Because of its subwavelength dimension, this electromagnetically induced transparency-like molecule can be used as a building ...
We measure magnetization changes in a single crystal of the single-molecule magnet Fe8 when exposed to intense, short (?20 ?s) pulses of microwave radiation resonant with the m = 10 to 9 transition. We find that radiation induces a phonon bottleneck in the system with a time scale of ~5 ?s. The phonon bottleneck, in turn, drives the spin dynamics, allowing observation of thermally assisted ...
