Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

Advanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Image segmentation in thermal images

2016 IEEE International Conference on Industrial Technology (ICIT), 2016
This paper presents a novel method for image segmenting in thermal images. A thermal imaging sensor is a device that forms an image by detecting the infrared radiation from objects in a scene and comparing their temperature differences. In this study, we characterized an object's heat signature (its mean temperature and variance) by segmenting its ...

Thermal imaging of composites

Journal of Microscopy, 2001
Active thermal imaging techniques and their applications to composite materials are reviewed. The techniques included are transient thermography, scanning thermal microscopy and scanning thermal probe microscopy. The factors that affect the images produced by both pulsed and periodic forms of active heating are considered.
