At ambient pressure tin transforms from its ground-state semi-metal $\alpha$-Sn (diamond structure) phase to the compact metallic $\beta$-Sn phase at 13$^\circ$C (286K). There may be a further transition to the simple hexagonal $\gamma$-Sn above 450K

The hexagonal structure of graphene gives rise to the property of gas impermeability, motivating its investigation for a new application: protection of semiconductor photocathodes in electron accelerators. These materials are extremely susceptible to

The complexity of photocathode designs and detector materials, and the need to model their performance for short pulse durations, the response to high-frequency photons, the presence of coatings and/or thinness of the absorptive layer, necessitates m

Tunneling barriers are an essential component of electron sources, sensors, detectors, and vacuum nanoelectronics and a pivotal factor in their performance, but the barriers themselves routinely depart from the analytic models used to model their beh

Optical Modeling and Performance Predictions IX.
Modeling photoemission using the Moments Approach (akin to Spicer’s “Three Step Model”) is often presumed to follow simple models for the prediction of two critical properties of photocathodes: the yield or “Quantum Efficiency” (QE), and th
