On‐Chip Microheater‐Based Back‐End‐of‐Line Compatible Synthesis of VO2 Films for Reconfigurable Silicon Photonics

Advanced Optical Materials, EarlyView.
A back‐end‐of‐line‐compatible microheater platform enables localized synthesis and reversible switching of high‐quality VO2 directly on silicon photonic chips. The approach overcomes conventional thermal‐budget and patterning constraints while delivering device performance comparable to high‐temperature‐grown films, providing a scalable pathway for ...

Plasma Induced Surface Nanostructure on Semiconductors for the Application Of Random Laser

2022 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR), 2022
Unique surface nanostructures were formed on semiconductors over a large area by Ar plasma irradiation with RF sample bias. As an application of these wavelength ordered size structure, we have demonstrated a random laser emission at UV region.

Surface effects in laser interaction with overdense plasmas

AIP Conference Proceedings, 2002
The dynamics and generation of surface structures in intense laser interaction with overdense plasmas is studied numerically and analytically. The dynamics of two-dimensional (2D) electron surface oscillations (ESOs) has been resolved in particle-in-cell simulations, showing a “period doubling” effect with respect to the driving magnetic force of the ...

Laser annealing of plasma-damaged silicon surface

Applied Surface Science, 2015
Abstract 13.56 MHz capacitance coupled Ar plasma irradiation at 50 W for 120 s caused serious damage at SiO2/Si interfaces for n-type 500-μm-thick silicon substrates. The 635-nm-light induced minority carrier effective lifetime (τeff) was decreased from 1.7 × 10−3 (initial) to 1.0 × 10−5 s by Ar plasma irradiation.
