An effect of sample bias voltage on analysis time and time resolution of a single-event three-dimensional time-of-flight (ToF) Rutherford backscattering spectrometry (RBS) was evaluated with both experiment and simulation. Fluctuations of trajectorie

Fine-Focus single-event time-of-flight (TOF) Rutherford backscattering spectrometry (RBS) was simulated using TRIM data together with own software. Electron- and ion trajectories were computed by taking geometric features and potential distribution w
An X-ray charge neutralizer using a screen-printed carbon-nanotube field emitter is demonstrated to show the possibility of a large-area flat-panel charge neutralizer, although the device dimensions in the present work are not very large. The X-ray y

We calculated temperature, polarization, charge,and potential of Laser-Irradiated pyroelectric crystal and reproduced the experiments. These calculated results suggest that the time-dependent radial distributions of surface charge and electric field
Graphene on a SiO$_2$/Si substrate was removed by ultraviolet pulsed laser irradiation. Threshold laser power density to remove graphene depended on the graphene thickness. The mechanism is discussed using kinetic energy of thermal expansion of the s

Volcano-structured p-type silicon field emitter arrays have been fabricated by etch-back technique and investigated the photoresponse characteristics of electron emission excited by laser pulses. We have observed the current pulses from the device wi
