Si-nanosheets (Si-NSs) have recently attracted considerable attention due to their potential as next-generation materials for electronic, optoelectronic, spintronic, and catalytic applications. Even though monolayer Si-NSs were first synthesized over 150 years ago via topotactic deintercalation of CaSi2, there is a lack consensus within the literature regarding structure optical properties this material. Herein, we provide conclusive evidence structural chemical produced by CaSi2 with cold...
Abstract The gold–sulfur (Au–S) and silver–sulfur (Ag–S) bonds are integral to the surface modification of metal films with alkanethiol monolayers. Although metal–sulfur bond can be characterized surface‐enhanced Raman spectroscopy (SERS) at roughened films, some applications require or perform better when using a smooth surface, which is not suitable for SERS signal enhancement. Directional‐surface‐plasmon‐coupled scattering (directional scattering) an approach measure on sub‐monolayer...
Germanium nanocrystals (Ge NCs) have potential to be used in several optoelectronic applications such as photodetectors and light-emitting diodes.
Directional-surface-plasmon-coupled Raman scattering (directional RS) has the combined benefits of surface plasmon resonance and spectroscopy, provides ability to measure adsorption monolayer-sensitive chemical information. Directional RS is performed by optically coupling a 50 nm gold film Weierstrass prism in Kretschmann configuration scanning angle incident laser under total internal reflection. The collected parameters on side interface include full surface-plasmon-polariton cone signal...
This paper presents a capacitive differential bridge structure with both AC and DC excitation balancing capability for low cost electrode-solution interfacial capacitance biosensing applications. The proposed series RC offers higher sensitivity, lower susceptibility to common-mode interferences, drift control. To evaluate the performance in practice, possible effects of initial imbalance due component mismatches are investigated considering required resolution networks, linearity. evaluation...
