Precise instruments for the next generation of LED chips

The path to new LED technologies is taken layer by layer and flooded with acid. Highly specialized cleanroom equipment is therefore needed to produce for example blue LEDs from gallium nitride (GaN) at the Institute of Semiconductor Technology at TU Braunschweig. Two new large-scale instruments now open up further avenues for semiconductor technology, from which QuantumFrontiers and the Quantum Valley Lower Saxony (QVLS) benefit in particular. Several years of work are behind this. After all, each of the devices has its own peculiarities that only an electron microscope can uncover.
