We will begin by defining some logical connectives. The first logical connective is implication. Luckily, implication is already built in to the Haskell type system in the form of arrow types. The type p -> q is equivalent to the logical statement P → Q. We can now prove a very simple theorem called Modus Ponens. Modus Ponens states that if P implies Q and P is true, then Q is true. It is often...

The integrated PL also increases with temperature in the same manner as the EL, indicating that the temperature dependence is intrinsic to the recombination, rather than the injection mechanism. The strong temperature quenching of PL and EL in most semiconductors is primarily the result of the strong temperature dependence of the compet...
