DOI: 10.1016/j.vacuum.2019.108968

Abstract: Abstract In this study, we developed a new sacrificial layer (SL) for laser transfer process. Metallic substrate i.e. invar foil was temporarily docked to a glass substrate using glass powder. To ensure successful delamination, the… read more here.

DOI: 10.1117/1.oe.60.8.087101

Abstract: A patterned laser lift-off technique is adopted for fabricating terahertz (THz) metamaterials with micrometer precision. A shaped UV laser pulse is used to remove low-viscosity silver nanopaste from a quartz substrate. Various types of metal… read more here.

DOI: 10.1364/ol.564940

Abstract: Due to the lack of a suitable substrate, high-quality semi-polar GaN is usually obtained through overgrowth on a patterned substrate, which endows the epitaxial film with an approximately periodic trend in both surface morphology and… read more here.

DOI: 10.35848/1882-0786/ac6567

Abstract: The centimeter-scale laser lift-off (LLO) of a UVB laser diode structure on nano-patterned AlN was demonstrated by using a 257 nm pulsed laser. The mechanism of this LLO, which can be used for vertical light-emitting… read more here.
