In a bipolar junction transistor, the length scale of this process limits the width of the base, and itoccurs in both directions across the junction.
In a bipolar junction transistor, the length scale of this process limits the width of the base, and itoccurs in both directions across the junction. A coefficient important to describing this process takesinto account tortuosity, porosity, and hindrance. A law describing this process states that its timeincreases with the square of the distance travelled, and another law describing it states that its flux isproportional to the negative gradient of the (*) chemical potential. Those two laws are named for Fick.When this process occurs across a semipermeable membrane with water, it is called osmosis. For 10 points,identify this process by which particles move from areas of high concentration to low concentration.
