Orbital Geometry‐Governed Response of Pressure‐Tunable Quantum Defects in hBN

open access: yesAdvanced Functional Materials, EarlyView.
Defects in hBN act as ultrasensitive quantum manometers when the energy of the intradefect optical transitions is modified by lattice compression. The orbital geometry of the electron wave functions governs how electron hopping and Coulomb interactions react uniquely to the reduction of the van der Waals gap and in‐plane compression, leading to robust ...

A CFD technique for estimating the flow distortion effects on LiDAR measurements when made in complex flow fields [PDF]

open access: yes, 2013
The effect of flow distortion on the measurements produced by a LiDAR or SoDAR in close proximity to either complex terrain or a structure creating localised flow distortion is difficult to determine by analytical means.
