A retrograde P-well may be formed using Boron diffusion followed by surface oxidation in order to reduce the Boron doping concentration at the surface of the well. However, the reduction in the P-type doping concentration at the surface of the retrograde well is typically not adequate to achiev...
The diffusion LED light has worked fine for me Dan. Is the light on the newer models subpar? With 16mm I use it at 80% light at get a f5.6 scan. I found with slight overscan with 8mm I can get by at f5.6 using 55mm extension tube instead of the 75mm tube I w...
Our study additionally suggests a cyclical conceptualisation of the diffusion of innovations model, or its extension to include a new group of retro-adopters.doi:10.1142/S1363919619400097Jack AdamsOzgur DedehayirTomi NokelainenJoe TiddWorld Scientific Publishing Co.

The resulting partial functional differential equation is similar to a Fokker–Planck equation, describing diffusion in a noisy environment, except that the diffusion matrix is not positive-definite, and has a zero trace. As a result, the trajectories obey a real action principle [59,60,61] of...
