Article Abstract

Photonic jets (PJs) are generated by the interaction between beams and dielectric particles, resulting in narrow, high-intensity beams produced behind the medium. Silicon nitride exhibits excellent optical properties; we aim to explore the potential of silicon nitride in PJ applications. In this paper, the beam is expanded by spherical vector wave functions with the framework of the generalized Lorenz-Mie theory (GLMT). Numerical simulations are performed to investigate the PJs generated by silicon nitride spherical particles illuminated by the plane wave, Gaussian beam, and zero-order Bessel beam under water; the effects of various parameters on the characteristics of PJs are further examined.

Electrochemiluminescence (ECL) imaging through closed bipolar nanoelectrode arrays (BPnEAs) has emerged as a promising method for in situ label-free wide-field electrochemical imaging. In this study, a cathodic ECL system based on [Ru(bpz)]/SO is combined with the BPnEAs fabricated on silicon nitride membrane windows through focused ion beam nanofabrication, enabling effective bipolar imaging of heterogeneous anodic electrocatalytic reactions. The shape, distribution, size, and material composition of individual electrodes within the array can be precisely controlled.

Hard entropy limits of impurity doping prevent further miniaturization of low nanoscale silicon-based very large scale integration (VLSI) devices, thereby obstructing the path toward more energy-efficient VLSI designs with higher yield in compute power. As demonstrated here by synchrotron UV photoelectron spectroscopy (UPS) and X-ray absorption spectroscopy in total fluorescence yield mode (XAS-TFY), intrinsic Si at the bottom of the nanoscale (i-nano-Si) turns into strong p- or n-Si by embedding in silicon nitride (SiN) or silicon dioxide (SiO), respectively. The associated Nanoscale Electronic Structure Shift Induced by Anions at Surfaces (NESSIAS) creates a p/n junction in i-nano-Si by the quantum-chemical impact of SiN- vs SiO-coating, providing energy landscapes to accumulate electrons (holes) when SiO- (SiN-) coated, with free charge carriers provided by metallic interconnects.

The quest for high-capacity anode materials is vital in developing future lithium-ion battery technologies. While silicon-based anodes offer high theoretical capacity, their commercial realization is hindered by instability associated with large volume changes. Amorphous silicon nitride (a-SiN) has emerged as a promising alternative, acting as a conversion-type anode where lithium incorporation drives the formation of a structurally robust matrix and active phases.

This article aims to utilize a microelectromechanical system (MEMS) to modulate coupling behavior of silicon nitride (SiN) waveguides to perform an optical switch based on a directional coupling (DC) mechanism. There are two states of the switch. First state, a SiN wire is initially positioned up suspended in the air.

We present a compact and polarization-insensitive 1 × N optical power splitter based on a non-uniform array of coupled silicon nitride waveguides. A 1 × 5 prototype is fabricated and tested with uniform power distribution with a low power imbalance across an 80 nm bandwidth in the C + L bands. The core splitting footprint is 13 m² per port.
