Optimization of THz Microscopy Imaging
Katherine A. Niessen, A.G. Markelz
TL;DR
This paper investigates the spatial and temporal response of ZnTe and GaP crystals in THz near field microscopy, highlighting factors affecting signal quality to improve high-resolution material imaging.
Contribution
It provides a detailed analysis of the response properties of ZnTe and GaP crystals, identifying causes of signal degradation in THz microscopy.
Findings
ZnTe shows degraded signal response compared to GaP.
Uniformity and reproducibility are crucial for high-resolution THz imaging.
Analysis suggests specific properties of ZnTe lead to signal degradation.
Abstract
THz near field microscopy opens a new frontier in material science. High spatial resolution requires the detection crystal to have uniform and reproducible response. We present the THz near field spatial and temporal response of ZnTe and GaP and examine possible properties that give rise to the ZnTe degraded signal.
