Ultrafast Multi-Shot Ablation and Defect Generation in Monolayer Transition Metal Dichalcogenides
Joel M. Solomon, Sabeeh Irfan Ahmad, Arpit Dave +5
Transition metal dichalcogenides are known to possess large optical nonlinearities and driving these materials at high intensities is desirable for many applications. Understanding…
Ultrafast Laser Ablation, Intrinsic Threshold, and Nanopatterning of Monolayer Molybdenum Disulfide
Joel M. Solomon, Sabeeh Irfan Ahmad, Arpit Dave +7
Laser direct writing is an attractive method for patterning 2D materials without contamination. Literature shows that the femtosecond ablation threshold of graphene across substrat…
Single-crystal hexagonal boron nitride monolayer epitaxially grown on Cu (111) thin film across a wafer
Tse-An Chen, Chih-Piao Chuu, Chien-Chih Tseng +9
We demonstrate single crystal growth of wafer-scale hexagonal boron nitride (hBN), an insulating atomic thin monolayer, on high-symmetry index surface plane Cu(111). The unidirecti…
