Frenkel Biexcitons Light Up Organic Semiconductor Advances
Organic semiconductors already provide the energy behind optical technologies inside television displays, solar cells, and lighting fixtures. Their molecular carbon-based structure makes them cheaper to produce, more flexible, of lighter weight, and more environmentally friendly than silicon-based or composite semiconductors. The future in more applications is bright — if scientists can learn more about harnessing their ability to react to and produce light.

This month we are highlighting the Keyence VK-X3000 3D Surface Profiler, which performs non-contact profile, roughness, and film thickness measurements with nanometer-level resolution on any material or shape. Unlike other 3D measurement systems, objects with steep angles or low-reflectivity can be accurately measured. It is the world’s first optical profiler to offer a triple scan approach, allowing users three different scanning methods in a single device: laser confocal, focus variation, and white light interferometry. The VK-X3000 also offers guaranteed measurement accuracy, high-speed scanning, and optimized optics to eliminate aberration.
