Diffusion, Osmosis, Active Transport
1) Passive a) Simple Diffusion b) Facilitated Diffusion c) Osmosis (water only) 2) Active a) Molecules b) Particles Diffusion Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of

For pure silicon, then n2 NN exp(E /kT) i = c V − G Thus n i = 9.6 109 cm-3 Similarly the Fermi level for the intrinsic silicon is, E i = E V +(E C − E V)/2+(1/2)kTln(N V / N C) Where we have used E i to indicate intrinsic Fermi level for Si.
