Identifying the source of solar chromospheric jets
Solar spicules are jets of cold dense material emerging through the Sun's lower atmosphere, the chromosphere. This work demonstrated these can be formed from MHD waves.
Ballistic One-Dimensional Holes with Strong g鈥慒actor Anisotropy in Germanium
Observation of ballistic 1D holes with strong g鈥慺actor anisotropy in epitaxial Germanium marks an important step toward the realization of novel devices for applications in quantum spintronics.
Determining crystal structure to high precision with electron diffraction
Until now, electron diffraction has not determined atomic positions in a crystal to the same accuracy (10^-13 m) as X-rays. We describe a new method which does this and more.
Quantitative High-Dynamic-Range Electron Diffraction of Polar Nanodomains in Pb2ScTaO6
Relaxor ferroelectrics have useful behaviour not yet fully understood. We used electron diffraction to show that ferroelectric behaviour in PST is actually due to two coupled antiferroelectric modes.
