Fabrication and characterization of single luminescing quantum dots
... silicon is the dominating platform for microprocessors and integrated circuits. As of today, the solar cell business is largely based on this material, as well. Being an indirect bandgap semiconductor, silicon could not be utilized as active material in lighting and photonics technology, though. Opt ...

The fuzzball paradigm for black holes: FAQ
... monopole is a nonperturbative construction, in the sense that if we had looked at perturbative solutions to the gauge field Aµ arising from the compact S 1 , then we would not have found this solution. This microstate was ‘simple’ because only 2 monopoles were involved, but there are states with mor ...
