Temporal characterization of femtosecond electron pulses inside ultrafast scanning electron microscope [PDF]
BIO Web of ConferencesIn this work, we present the implementation of all-optical method for directly measuring electron pulse duration in an ultrafast scanning electron microscope. Our approach is based on the interaction of electrons with the ponderomotive potential of an optical standing wave and provides a precise in situ technique to characterize femtosecond electron ...

Mapping the potential within a nanoscale undoped GaAs region using a scanning electron microscope [PDF]
Appl. Phys. Lett. Vol 84, pp. 2109-2111, 2004, 2004 Semiconductor dopant profiling using secondary electron imaging in a scanning electron microscope (SEM) has been developed in recent years. In this paper, we show that the mechanism behind it also allows mapping of the electric potential of undoped ...

Nanoscale tip positioning with a multi-tip scanning tunneling microscope using topography images [PDF]
Review of Scientific Instruments 93, 013702 (2022), 2022 Multi-tip scanning tunneling microscopy (STM) is a powerful method to perform charge transport measurements at the nanoscale. With four STM tips positioned on the surface of a sample, four-point resistance measurements can be performed in dedicated geometric configurations.
