Band Alignment of Grafted Si/Ge0.89Sn0.11 Heterojunction Determined by X‐Ray Photoelectron Spectroscopy

Advanced Materials Interfaces, EarlyView.
ABSTRACT We investigate the band alignment of a monocrystalline grafted p‐type Si/Ge0.89Sn0.11 heterostructure using X‐ray photoelectron spectroscopy (XPS). The bandgap of the Ge0.89Sn0.11 epilayer of 0.50 eV was first determined and cross‐verified using photoluminescence spectroscopy, infrared transmission, and theoretical calculation.

A novel GIS breakdown location method based on natural frequency of transient voltage

High Voltage
During on‐site withstand voltage tests of gas‐insulated switchgears (GIS), once a breakdown occurs, it is hard to locate the breakdown position due to the intricate branch structures and minimal breakdown energy.

Architecture of petawatt-class z-pinch accelerators

Physical Review Special Topics. Accelerators and Beams, 2007
We have developed an accelerator architecture that can serve as the basis of the design of petawatt-class z-pinch drivers. The architecture has been applied to the design of two z-pinch accelerators, each of which can be contained within a 104-m-diameter
