Importance of charge capture in interphase regions during readout of charge-coupled devices [PDF]
The current understanding of charge transfer dynamics in charge-coupled devices (CCDs) is that charge is moved so quickly from one phase to the next in a clocking sequence and with a density so low that trapping of charge in the interphase regions is ...

A computational study on the charge-trapping characteristics of nano-silica-doped polydimethylsiloxane composites [PDF]
Widely used as an insulating material in power cables, polydimethylsiloxane (PDMS) requires improved dielectric properties. Doping with nanoparticles is recognized as a feasible modification method, in which changes in charge-trapping characteristics are

Investigating charge trapping in ferroelectric thin films through transient measurements
A measurement technique is presented to quantify the polarization loss in ferroelectric thin films as a function of delay time during the first 100s after switching. This technique can be used to investigate charge trapping in ferroelectric thin films by

Hysteresis-Free Nanosecond Pulsed Electrical Characterization of Top-Gated Graphene Transistors [PDF]
We measure top-gated graphene field effect transistors (GFETs) with nanosecond-range pulsed gate and drain voltages. Due to high-k dielectric or graphene imperfections, the drain current decreases ~10% over time scales of ~10 us, consistent with charge ...

Improved charge-trapping properties of HfYON film for nonvolatile memory applications in comparison with HfON and Y 2O 3 films [PDF]
The charge-trapping properties of HfYON film are investigated by using the Al/HfYON/SiO 2/Si structure. The physical features of this film were explored by transmission electron microscopy and x-ray photoelectron spectroscopy.
