The Institute of Solid State Physics at Technische Universität Berlin (TUB) performs research in the area of solidstate materials and devices including epitaxy of semiconductor heteroand nanostructures, the exploration of new materials such as carbon nanotubes and graphene, and the development of nanophotonic and electronic devices such as laser diodes, semiconductor optical amplifiers, UVLEDs,VCSELs, singlephoton emitters, and nanoflash memories. The activities span from basic research to applications and incubated several successful spinoffs.
FBH and TUB (Joint Lab GaN Optoelectronics) have a 10+ year history on developing LEDs and laser diodes based on (Al,In,Ga)N. By covering the complete processing chain from heterostructure design, AlN on sapphire growth, heterostructure growth, chip processing, packaging and device characterization including reliability testing, they have developed UV LEDs in an extremely wide wavelength range from 380 nm down to 217 nm with worldclass performance.
In the tour we will visit TUB’s labs for metalorganic vapor phase epitaxy and characterization of UV-LEDs and UV emitting materials. We will explain the inner structure and working principles of UV-LEDs, show how the semiconductor crystal is grown and how LED chips ready for applications are fabricated. Also we will give an insight how researchers at TUB analyze the LEDs to understand the internal processes in the LEDs for improving their performance and lifetime.
