Drawing a clear and compelling figure is vital in science communication, so Karen Cheng and Marco Rolandi set up a help desk for scientists and engineers to consult with design students.
The electronic, chemical and mechanical properties of quantum dot structures may lead to thermoelectric devices with a range of advantages with respect to existing ones based on bulk polycrystalline materials.
Although research into colloidal quantum dots has led to promising results for the realization of photovoltaic devices, a better understanding of the robustness and stability of these devices is necessary before commercial competiveness can be claimed.
Synthesis of semiconductor colloidal quantum dots by low-cost, solution-based methods has produced an abundance of basic science. Can these materials be transformed to high-performance light emitters to disrupt established photonics technologies, particularly semiconductor lasers?
