Homogeneous Large Area CVD-Diamond Detectors for Tracking and ToF
In the last year, we continued with the development of large-area diamond sensors grown at the University of Augsburg by chemical vapour deposition (CVD) on wafer scale Ir/YSZ/Si(001) substrates. Early results of diamondon-iridium (DoI) sensors [1] were indicating significant defect densities within the detector bulk, which led to reduced charge collection efficiencies CCE = QColl/QGen= 40% (wi...
متن کاملUV photoemission efficiency of polycrystalline CVD diamond films
The absolute quantum efficiency of polycrystalline diamond films grown on silicon substrates by chemical vapor deposition (CVD) is reported in the range of 25–200 nm. The efficiency of boron-doped and hydrogen-activated by microwave plasma reflective photocathodes peaked at 37% at 40 nm with the sensitivity cutoff observed at ~190 nm. We confirmed that hydrogen activation is relatively stable i...
متن کاملDevelopment of large area polycrystalline diamond detectors for fast timing application of high-energy heavy-ion beams
We have studied the effects of electrode fabrication and detector capacitance on the time resolution of large area electronic grade polycrystalline diamond sensors, made using chemical vapour deposition, that are suitable for time of flight measurements of heavy ions at relativistic velocities. Sensors were prepared both in house, with Al or Au metal contacts, and commercially fabricated with A...
متن کاملRole of Molecular Sieves in the CVD Synthesis of Large- Area 2D MoTe2
© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim wileyonlinelibrary.com (1 of 8) 1603491 In this family, thin layers of transition metal dichalcogenides (TMDs) with the formula MX2 (M = transition metal of group 4–10; X = S, Se, or Te) are particularly attractive for optoelectronics applications.[7,8] For example, several bulk TMDs are indirect bandgap semiconductors, but will become direct ba...
متن کاملParamagnetic Intrinsic Defects in Polycrystalline Large-Area 2D MoS2 Films Grown on SiO2 by Mo Sulfurization
A low-temperature electron spin resonance study has been carried out on large-area high-purity polycrystalline two-dimensional few monolayer (ML) 2H MoS2 films synthesized by sulfurization of Mo layers, with intent to atomically assess mobility-degrading detrimental point defects. This reveals the presence of a distinct previously unreported anisotropic defect of axial symmetry about the c-axis...
