We have studied the magnetic field 50 T dependence of the photoluminescence PL of self-assembled InAs /GaAs quantum dots as a function of temperature T . As the temperature is raised from 4.2 up to 80 K, thermal redistribution causes the PL to be increasingly dominated by dots with a lower PL energy. Magneto-PL demonstrates that these low-energy dots are(More)
We demonstrate the impact of reducing agents for Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) of WS2 from WF6 and H2S precursors. Nanocrystalline WS2 layers with a two-dimensional structure can be obtained at low deposition temperatures (300-450 °C) without using a template or anneal.
We have investigated the photoluminescence (PL) of two carefully selected dilute nitride Ga1−xInxNyAs1−y multiple quantum well structures in magnetic fields up to 50 T as a function of temperature and excitation power. The observation of a nonmonotonic dependence of the PL energy on temperature indicates that localized states dominate the luminescence at(More)

Two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) are of great interest for applications in nano-electronic devices. Their incorporation requires the deposition of nm-thin and continuous high-k dielectric layers on the 2D TMDs. Atomic layer deposition (ALD) of high-k dielectric layers is well established on Si surfaces: the(More)
B-doped diamond has become the ultimate material for applications in the field of microelectromechanical systems (MEMS), which require both highly wear resistant and electrically conductive diamond films and microstructures. Despite the extensive research of the tribological properties of undoped diamond, to date there is very limited knowledge of the wear(More)
