چکیده
Differential reflectance spectroscopy (DRS) is a powerful tool to study processes during thin-film growth, especially that of transition metal dichalcogenides and organic thin films. To satisfy the requirements for in situ real-time monitoring film including spectral resolution sensitivity at level monolayers even sub-monolayers, most challenging technical task DRS reduce noise an extremely low so best possible signal-to-noise ratio can be achieved. In this paper, we present simplified cost-effective apparatus, with which show measurement mainly composed thermal drift explore temperature-dependence signal. Based on results obtained, propose easily realized effective scheme aiming noise. Experimental demonstrate stabilizing reliable signals long period several hours. Significant reduction achieved, typical average system being decreased 0.05% over The improved applied growth semiconductor layer field-effect transistor device. indicate apparatus proposed paper has potential applications fabrication devices nanoscale sub-nanoscale.

A numerical method for solving delay-fractional differential and integro-differential equations
This article develops a direct method for solving numerically multi delay-fractional differential and integro-differential equations. A Galerkin method based on Legendre polynomials is implemented for solving linear and nonlinear of equations. The main characteristic behind this approach is that it reduces such problems to those of solving a system of algebraic equations. A conver...

An Effective Method on Reducing Measurement Noise Based on Hilbert-Huang Transform
For non-stationary signal in ultrasonic inspection, an effective denoising method based on Hilbert-Huang transform (HHT) is presented and a few key questions using the HHT method are discussed. The overall scheme of HHT includes two parts which are empirical mode decomposition (EMD) algorithm and a sum of intrinsic mode functions (IMF). Through the EMD process, individual IMF can be found. The ...
