Improved graphene-base heterojunction transistor with different collector semiconductors for high-frequency applications


New research paper from TU Dresden & others. Abstract "A new kind of transistor device with a graphene monolayer embedded between two n-typesilicon layers is fabricated and characterized. The device is called graphene-base heterojunction transistor (GBHT). The base-voltage controls the current of the device flowing from the emitter via graphene to the collector. The transit time for e... » read more

A freeze-thaw molten salt battery for seasonal storage


New research paper from Pacific Northwest National Laboratory. Abstract "Grid-level storage of seasonal excess can be an important asset to renewable electricity. By applying the freeze-thaw thermal cycling strategy, here, we report Al-Ni molten salt batteries with effective capacity recovery over 90% after a period of 1–8 weeks as a proof-of-concept. We explore three activation methods... » read more

Highly efficient modulation doping: A path toward superior organic thermoelectric devices


New academic paper from TU Dresden. Abstract "We investigate the charge and thermoelectric transport in modulation-doped large-area rubrene thin-film crystals with different crystal phases. We show that modulation doping allows achieving superior doping efficiencies even for high doping densities, when conventional bulk doping runs into the reserve regime. Modulation-doped orthorhombic rubr... » read more

Quantum logic with spin qubits crossing the surface code threshold


New research paper from QuTech, Delft University of Technology. Abstract "High-fidelity control of quantum bits is paramount for the reliable execution of quantum algorithms and for achieving fault tolerance—the ability to correct errors faster than they occur. The central requirement for fault tolerance is expressed in terms of an error threshold. Whereas the actual threshold depends o... » read more
