TīmeklisSurface Area:Volume Ratio • This gives an approximate surface area to volume ratio of >10. 7:1 which is significantly larger than a macro sized particle. • As the surface area to volume ratio increases so does the percentage of atoms at the surface and surface forces become more dominant. • Generally accepted material properties are TīmeklisThe Width for the NMOS is set to a workable minimum like 200 nm, that depends on the process. As PMOS transistors are intrinsically weaker they need a wider Width compared to the NMOS. Usually 2x wider is a good start so 400 nm for example. You could also make a much slower/low power version by increasing the value of L.
