Slow Hot Carrier Cooling and Quasi‐Fermi Shift Dynamics in Few‐Layer α‐In2Se3 via Transient Absorption Spectroscopy

open access: yesAdvanced Optical Materials, EarlyView.
Ultrafast transient absorption spectroscopy reveals that α‐In2Se3, a non‐toxic and air‐stable 2D material, demonstrates slow hot carrier (HC) cooling (≈35 ps), comparable to perovskites. This prolonged cooling can enable efficient energy extraction. Comprehensive analysis captures key HC dynamics, such as quasi‐Fermi shifts, many‐body interactions, and

A Confession of a Blonde Asian Girl

open access: yes, 2014
I never realized I was an Asian. Nor was I aware I was from South Korea. The thought of identifying myself as Asian was redundant for I was, indeed, from Asia where Asian people lived.

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

open access: yesAdvanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

Origin of the Laser‐Induced Picosecond Spin Current Across Magnetization Compensation in Ferrimagnetic GdCo

open access: yesAdvanced Optical Materials, EarlyView.
Picosecond spin current pulses generated by ferrimagnetic GdCo are studied via THz emission spectroscopy. Due to the GdCo micromagnetic structure, the spin current vanishes at compensation when a magnetic field is applied but persists for zero field. At room temperature, the THz spin current is dominated by Co. At low temperatures, Gd can significantly
