0D Nanocrystals as Light‐Driven, Localized Charge‐Injection Sources for the Contactless Manipulation of Atomically Thin 2D Materials

open access: yesAdvanced Photonics Research, 2021
A contactless charge‐injection scheme that allows the local and quasi‐permanent manipulation of atomically thin 2D materials, such as monolayer (1L‐)MoS2, over spatial extents of several tens of micrometers, is reported.

Currents Induced by Injected Charge in Junction Detectors [PDF]

open access: yesSensors, 2013
The problem of drifting charge-induced currents is considered in order to predict the pulsed operational characteristics in photo-and particle-detectors with a junction controlled active area. The direct analysis of the field changes induced by drifting charge in the abrupt junction devices with a plane-parallel geometry of finite area electrodes is ...

Charge Exchange Injection at the AGS [PDF]

open access: yesIEEE Transactions on Nuclear Science, 1983
The AGS has been brought into operation in October 1982 with multi-turn H- charge exchange injection. The injection area of the AGS has been modified to bring the H- beam from the 200 MeV linac through the main magnet fringe field to a stripping foil located within the magnet aperture. The injection system is described in detail and initial performance
