cfaed's Chair for Network Dynamics (Prof. M. Timme), in cooperation with several scientific groups in Göttingen and Cape Town/South Africa, investigated the conditions of the spread of COVID-19 cases in countries of the Gobal South. Their scenario analysis for a region in South Africa combines statistical socio-economic and travel survey data from more than 100,000 individuals, based on employment status, household size, age group and income level together with a detailed 24-hour travel diary component and integrates them into an agent-based traffic simulation of the ongoing COVID-19 outbreak in the Nelson Mandela Bay Municipality. The findings suggest that countermeasures are required to be especially rapid and severe to keep the number of critical patients below the capacity set by locally available intensive care units (ICUs).

Digital cameras as well as many other electronic devices need light-sensitive sensors. In order to cater for the increasing demand for optoelectronic components of this kind, industry is searching for new semiconductor materials. They are not only supposed to cover a broad range of wavelengths but should also be inexpensive. A hybrid material, developed in Dresden, fulfills both these requirements. Himani Arora, a physics PhD student at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), demonstrated that this metal-organic framework can be used as a broadband photodetector. As it does not contain any cost-intensive raw materials, it can be produced inexpensively in bulk.

It already belongs to the Cluster’s classics: The microelectronics summer school "Dresden Microelectronics Academy" at cfaed will - hopefully - also take place in 2020. Even if, in view of the current crisis, it is not yet possible to look reliably into the future, the organizers at cfaed and the semiconductors industry are optimistic and continue to push ahead with the planning of this unique summer school. Registrations are now possible. As always, places are limited, as the exclusive insights into production and processes at industry giants Globalfoundries, X-FAB, Infineon or Bosch can only be gained with small groups.

The "Taicang High-Tech Park" near Shanghai (China) is donating 10,000 urgently needed respiratory protective masks to TU Dresden and its Carl Gustav Carus University Hospital.
"We are extremely grateful for this gesture of friendship and this strong signal of international solidarity and I am personally deeply touched", says Prof. Hans Müller-Steinhagen, Rector of TU Dresden. "In times of need, such a humanitarian gesture has a significance that goes far beyond its mere material value."

Scientists at TU Dresden and Hasselt University in Belgium investigated the physical causes that limit the efficiency of novel solar cells based on organic molecular materials. Currently, the voltage of such cells is still too low - one reason for their still relatively low efficiencies. In their study, by investigating the vibrations of the molecules in the thin films, the scientists were able to show that very fundamental quantum effects, so-called zero point vibrations, can make a significant contribution to voltage losses. The study has now been published in the journal Nature Communications.
