Nano-antennas assist in improving spatial resolution of terahertz microscopy
A team lead by a LCN researcher has demonstrated a detector for terahertz waves with integrated optical nano-antennas. The detector enables enhanced spatial resolution in terahertz microscopy. Similar to more commonly used infra-red waves and X-rays, terahertz waves...
A coherent look at crystalline defects
A ‘lensless’ X-ray microscope has captured, in stunning detail, the first three-dimensional images of crystalline defects during crystal growth of a mineral, calcite. The ‘lensless’ microscope allowing this 3D imaging was pioneered by the group of Ian Robinson at the...
Transient melting of a nanocrystal: seeing is believing
Jesse Clark, working as a postdoc in the LCN group of Ian Robinson, has discovered a spectacular transient melting phenomenon in nanocrystals. Coherent X-ray diffraction experiments, carried out at the LCLS X-ray free electron laser facility at Stanford, have allowed...
