This product is a 60W solar LED street lamp. Compared with those LED street lamps on the market, it has the advantages of power saving, durability, easy installation and zero wiring.
The carrier density of a semiconductor changes with the activation temperature of the activation energy E2. A line represented by the Arrhenius plot is a straight line; but what is the change rule for doped semiconductors? Tian 1 is the electron density of the n-type semiconductor
Niusto. Please note that the abscissa of Figure 1 is 1/T, the lower the temperature to the right.
Generally speaking, semiconductors include both donors and acceptors. When the donor density N is larger than the acceptor density N, the acceptor is buried by the donor electron (this case is called compensation), N. -N is the net donor density.
