We present a new method for measuring the coefficient of restitution between a steel ball and a flat, smooth surface, based on the recording of sound files with a PC. We demonstrate how a simple and straightforward analysis of the sound files yields

We present measurements of the electrical conductance through breaking point contacts in commercial and home-built electromechanical relays under ambient conditions. Inspired by an experiment published by Costa-Kr\"amer et al. [Surf. Sci. 342, L1144

Two samples of illite-smectite (I-S) isolated from Upper Jurassic clays in well 2/7-3 (3365 m) and well 2/11-1 (4548 m) have been investigated by scanning tunnelling microscopy (STM), and the particle shape and dimensions have been correlated to resu

We present measurements of current-voltage (I-V) curves on gold quantum point contacts (QPCs) with a conductance up to 4 G(0) (G(0) = 2e(2)/h is the conductance quantum) and voltages up to 2 V. The QPCs are formed between the gold tip of a scanning t

We present experimental and theoretical results for the conductance and mechanical properties of atom-sized wires between two metals. The experimental part is based on measurements with a scannng tunneling microscope (STM) where a point contact is cr

We present direct measurements at room temperature of the conductance of a point contact between a scanning tunneling microscope tip and Ni, Cu, and Pt surfaces. As the contact is stretched the conductance jumps in units of 2${\mathit{e}}^{2}$/h. Ato

Implantation of Sn at ∼550°C into SiC and post-annealing at 1120°C has been demonstrated to lead to a predominant population of the substitutional Si sites. The electronic structure of the Sn atoms in substitutional Si sites has been shown to be
