Dielectric breakdown and sub-wavelength patterning of monolayer hexagonal boron nitride using femtosecond pulses
Sabeeh Irfan Ahmad, Emmanuel Sarpong, Arpit Dave +6
Hexagonal boron nitride (hBN) has emerged as a promising two-dimensional (2D) material for many applications in photonics. Although its linear and nonlinear optical properties have…
High-speed scanless entire bandwidth mid-infrared chemical imaging
Yue Zhao, Shota Kusama, Yuji Furutani +3
Mid-infrared spectroscopy probes molecular vibrations to identify chemical species and functional groups. Therefore, mid-infrared hyperspectral imaging is one of the most powerful…
Ultrafast spintronics with geometric effects in non-adiabatic wave-packet dynamics
Matisse Wei-Yuan Tu, Li-Sheng Lin, Chung-Yu Wang +6
Motivated by the intriguing possibilities of steering ultrafast non-adiabatic processes through the geometric properties of bands in quantum materials by laser pulses, we extend a…
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…
Unveiling the hidden nematicity and spin subsystem in FeSe
C. W. Luo, P. C. Cheng, S. -H. Wang +7
The nematic order (nematicity) is considered one of the essential ingredients to understand the mechanism of Fe-based superconductivity. In most Fe-based superconductors (pnictides…
