Laser-Ablated Nanomaterials and Porous Silicon for Sensing, Photodetection and Solar Energy
This community develops nanostructured materials—primarily silicon, germanium, and III-V semiconductors—using laser ablation and deposition techniques, targeting applications in chemical and biological sensing, photodetection, and solar energy conversion.
The work centers on the synthesis of porous silicon, silicon nanowires, and core-shell nanoparticles via pulsed laser ablation in liquids and deposition. Recurring methods include laser desorption ionization and mass spectrometry for material characterization, alongside the fabrication of thin films and photonic crystals. Applications span gas sensing, electrochemical biosensing, and the construction of solar cells and photodetectors. The research frequently combines silicon with germanium and gallium arsenide to create heterostructures, while also exploring the use of these nanostructures as substrates for enhanced detection of chemical and biological analytes.
The community is most heavily represented in research on silicon and germanium, accounting for 4.5% and 4.9% of all tracked research for those elements, respectively. Silicon also contributes the highest number of papers to this group, with 1,675 entries.
The community comprises 6,399 papers, published predominantly in Applied Physics Letters, Journal of Applied Physics, and Nanotechnology. Recent work continues to focus on laser-ablated nanoparticles for photodetectors, porous silicon-based biosensors, and III-V nanowire solar cells.
