Particle trapping and binding in optical potential wells provide a versatile platform for various biomedical applications. However, implementation systems to study multi-particle contact interactions an lattice remain rare. By configuring optofluidic lattice, we demonstrate the precise control of particle functions such as controlling aggregation multi-hopping. The mean residence time single is found considerably reduced from 7 s, predicted by Kramer's theory, 0.6 owing mechanical among...
Because of the nonequilibrium nature thermal effects at nanoscale, characterization local within a single molecule is highly challenging. Here, we demonstrate way to characterize properties fullerene (C 60 ) during current-induced heating processes through tip-enhanced anti-Stokes Raman spectroscopy. Although measured vibron populations are far from equilibrium with environment, can still define an “effective temperature ( T eff )” statistically via Bose-Einstein distribution, suggesting...
We present an optofluidic chip consisting of a quasi-Bessel beam for multi-range separation sub-100 nm gold nanoparticles and pathogens with microscopic vibration.
Optofluidic lens with hyperbolic secant index profile, leading to low spherical and field curvature aberrations.
In this study, the crystal structure and magnetic properties of La$_{2-x} A'_{x}$Ni$_{7}$ compounds with rare earth elements ($A$' = Sm, Gd) have been investigated combining X-ray powder diffraction measurements. These intergrowth crystallize in a mixture 2$H$ hexagonal (Ce$_{2}$Ni$_{7}$-type) 3$R$ rhombohedral (Gd$_{2}$Co$_{7}$-type) polymorphic structures which are related to stacking [$AB_{5}$] [$A_{2}B_{4}$] subunits along $c$-axis.The average cell volume decreases linearly versus $A$'...
The paper reports the tensile strength measurement using an optofluidic chip based on displacement of air–water interface deformation with homogeneous nucleation.
We report a real-time method to determine the size, i.e. diameter, and refractive index of single gold nanoparticles using an optofluidic chip, which consists quasi-Bessel beam optical chromatography. The tightly focused (∼ 0.5 μm) with low divergence (NA ∼ 0.04) was used trap sub-100 nm within long trapping distance 140 μm. In experiment, 60 100 were separated efficiently at least 18 diameter (real imaginary) measured high resolutions respect distance, 0.36 nm/μm, 0.003/μm 0.0016/μm, respectively.
In this paper, we present a unified compact model (Xsim) that is based on drift-diffusion/surface-potential (DD/SP) formalism for Si-bulk/SOI MOSFETs by incorporating 2-dimensional electron gas (2DEG) extension to generic III-V MIS-HEMTs. The has been validated with TCAD and experimental data GaN-based HEMTs nanometer gate lengths. Digital (inverter/ring-oscillator) analog (cut-off frequency) circuit performance prediction GaN devices are also demonstrated. ultimate goal develop scalable...
