Effective charge compensation of europium in hafnium oxide nanoparticles was achieved at low temperature, allowing high doping incorporation (up to 6 at.%) and enhanced luminescence. The efficiency the confirmed by scanning electron microscope energy dispersive X-ray spectroscopy powder diffraction measurements. Despite known polymorphism oxide, when doped a concentration above 3 at.%, only pur...

Piezoelectric force microscopy (PFM) has demonstrated to be a powerful tool characterize ferroelectric materials. However, extrinsic effects, most notably, those resulting from surface charges, often mask or mirror genuine piezoelectric response, challenging PFM data understanding. The contribution of charges signal is commonly compensated by using appropriate external bias voltage, which ad-ho...

A charge-successive integrator (CSI) VLSI with a wide dynamic range has been developed for the front-end electronics of the Telescope Array project. The CSI has more than a 14-bit dynamic range and successively integrates the charge from a photomultiplier tube every 200 ns. We have newly designed an offset-compensated charge integrator to reduce the offset voltage and the 1 noise. We expect tha...
