We analyze the temperature dependence of the light output power of terahertz quantum cascade lasers (THz-QCLs) and demonstrate an enhancement of the stimulated emission rate triggered by thermally activated electron leakage from the lower laser level into the continuum. Contrary to common sense expectation, we find that this leakage channel contributes… (More)
The wood-degrading fungus Phanerochaete chrysosporium secretes a number of extracellular enzymes called lignin peroxidases which are involved in the degradation of both lignin and a number of persistent environmental pollutants. Lignin peroxidase isozyme H2, a glycosylated protein of approximately 40 kDa, contains a single heme. X-ray absorption… (More)
