Numerical integration/Gauss-Legendre Quadradure by MATLAB
江普庆 2013-10-19 13:11
Numerical integration/Gauss-Legendre Quadrature In a general Gaussian quadrature rule, a definite integral of f ( x ) is first approximated over the interval by a polynomial approximatedfunction g ( x ) and a known weighting function W ( x ). ...

信号的频域分析——傅里叶变换
江普庆 2013-10-1 14:07
Frequency-domain analysis is a tool of utmost importance in signal processing applications. While time-domain analysis shows how a signal changes over time, frequency-domain analysis shows how the signal's energy is distributed over a range of frequencies. A signal can be converted be ...

Silicon wafer cleaning recipe
江普庆 2013-7-19 16:27
General Clean: General cleaning is accomplished by using a mixture of Sulfuric Acid and Hydrogen Peroxide . Mixing these chemicals is dangerous and generates extreme heat. This industry standard clean removes organic and inorganic contamination from the wafer. 2~10 minute clean is rec ...

热穿透深度(thermal penetration depth)的推导
江普庆 2013-7-11 22:05
Periodic heating on the surface of a semi-infinite body induces an exponentially decaying temperature profile with a thermal penetration depth which identifies the depth normal to the surface at which the temperature amplitude is of its surface amplitude. This concept is commonl ...

声子的非弹性散射
江普庆 2013-7-9 15:30
Inelastic scattering processes arise due to the anharmonic nature of inter-atomic potential energy. For a harmonic oscillator, the spring constant is independent of spring deformation. However, this is not the case for the bonds between atoms, where the bond spring constant can change if th ...

《单晶硅中声子的平均自由程分布》
江普庆 2013-7-9 15:08
Abstract: Mean-free paths of phonons are crucial for understanding heat transport in micro/nano-structured materials like nanowires, superlattices and graphene. However, very little is known about the mean free paths of phonons, even for bulk silicon that is the most common material in semico ...
