The formation of gold wires separated by a few nanometres is reported. Such nanometre-separated gaps are formed by ramping, at ambient conditions, a bias voltage across a thin gold wire until the wire breaks or fails. Externally heating the wire does

Self-assembled monolayers (SAMs) formed by dissymmetric tetrathiafulvalene (TTF) derivatives on gold (111) are prepared, and the structural and electrical properties have been studied. The TTFs are united to the metal through two S−Au bonds while t

Lithium monosilicide (LiSi) was formed at high pressures and high temperatures (1.0–2.5 GPa and 500–700°C) in a piston-cylinder apparatus. This compound was previously shown to have an unusual structure based on 3-fold coordinated silicon atoms

Using a recently developed method for tethering gold contacts to single molecules, we have measured current versus voltage (I−V) data for single carotenedithiol molecules with a total length of 28 carbons (18 in the conjugated alkene chain). The mo

We report here the synthesis and structural characterization of two Structure I clathrates in the K–Si and Rb–Si systems. As observed previously for Na 8 Si 46 , the alkali-Si clathrates are fully stoichiometric at the framework sites, i.e., devo

Synthesis of a guest-free clathrate form of crystalline silicon was achieved by successive vacuum treatment and density separation of ${\mathrm{Na}}_{x}{\mathrm{Si}}_{136}$-based materials. The new allotrope of silicon has an open framework structure

Alloys based on Ge clathrates are promising thermoelectric materials because of their expected “rattling” properties. We have incorporated the elements of columns I and II into the cages of (Ge, Ga)46 type-I clathrates as cation guests and have t

The compressional behaviour of a new expanded form of silicon, the cubic Si136 clathrate, is studied by energy dispersive x-ray diffraction in a diamond anvil cell experiment. The ambient temperature bulk modulus and its pressure derivative are deter

The ${}^{29}\mathrm{Si}$ magic angle spinning NMR spectrum of ${\mathrm{Na}}_{8}{\mathrm{Si}}_{46}$ exhibits three resonances with large positive Knight shifts assigned to the inequivalent $(16i,$ $6c,$ and $24k)$ Si sites in the structure. The integ

We report on the synthesis and characterization of two silicon clathrates, Na 8 Si 46 and Na x Si 136 ( x =4–23), by powder X-ray diffraction, combined with Rietveld profile analysis. In Na 8 Si 46 , no deviation from the ideal stoichiometry is obs
