[交流] 可用于文章发表的free半导体计算软件

这些内容可是我几年来慢慢找到的！
希望对同行的人有用！现在能有这样的软件真是少之又少了。
希望你下载后，记得顶下我啦！我还有更好的资料。希望大家进步！！
能带计算软件

1）Simwindows 可用于论文发表的（全世界难得这好的软件可用，不用花钱的，）

http://ece-www.colorado.edu/~bar ... mwindows/sim150.exe

该软件用于计算半导体能带，激光器谐振腔反射、DBR，功能强大的，安装完内有英语说明书

2）1D Poisson 可用于发表论文的
介绍：
1D Poisson is a program for calculating energy band diagrams for semiconductor structures. It is a FreeWare program that I've written which solves the one-dimensional Poisson and Schrodinger equations self-consistently. The program is quite user friendly, and runs on a Macintosh. Click below to download an archive containing a version of the program for PowerMacs (very fast), a universal version (very slow!), and associated files. A version that runs in Classic mode under OS X is also available for download. Send email if you need a version for '030 or '040 Macs. A PC version for Windows 95 and up is also available. It is still under development, but it has all the same features and uses the same files as the Mac version.

3） Band Engineering  可用于发表论文的
介绍：
First load the included materials database file using Materials->Open...
Use Layers->New... to add a layer.  Note that "dx" is the grid spacing.  All thicknesses are in angstroms and the charge concentrations are in cm^-3.
Choose a material and doping.  Make sure you don't use zero for all dopings, or the solver will fail.  If you want no doping, use a very small number instead of zero.
Hit OK to add the layer, the band diagram should appear in the upper right corner.
The bottom of the screen shows important information.  The solver error should be less than 10e-5.  Additionally, you can find out local charge properties by dragging your cursor along the bottom right hand pane of the window.
Use File->Export... to export the band diagram into a file format that is easily readable by Excel, Origin, etc...
There is a lot more functionality, so play around.  The worst thing that can happen is a crash.
The program will have serious problems on some structures with large polarization charges - I'm still working on that.  (Update, if it's not converging, i.e. the number of iterations is the same as the max number of iterations, try playing with the setup->solver properties damping factor.  .9 usually helps...)
