Maxwell distribution law

November 11th, 2016

Maxwell distribution of velocities of the molecules has the form:

f(v)=(\frac{m_0}{2\pi kT})^\frac{3}{2}exp(-\frac{m_0 v^2)}{2 kT}) 4 \pi v^2 (1)

Optical semiconductors

October 18th, 2016

The training of specialists in the field fiber-optic communication lines involves the study of such difficult topics as “Light-emitting diode (LED)” and “Semiconductor Lasers” (Zvelto, 1990). Clarification of the physical foundations of these devices requires the use of educational information which is studied in the course of quantum chemistry. Read the rest of this entry »
