Abstract:
Herein, a promising infrared nonlinear optical (IR NLO) material, Li2ZnGeS4, was successfully synthesized in the typical quaternary diamond-like semiconductor (DLS) system. This material exhibits excellent performances including a wide band gap (3.49 eV), a high laser-damage threshold (LDT, 8 × benchmark AgGaS2), and a good NLO effect (0.7 × AgGaS2) with phase-matching behavior. Furthermore, based on first principles calculations, the theoretical results are in agreement with the experimental results.

Harmonic Mean
Take the example of the speed of a car, which is the measure of the rate of distance traveled. If the vehicle traverses the same distance back-and-forth, its average speed equals the total distance traveled divided by the total time taken. However, if the car moves with varying speeds, then the arithmetic mean is more skewed...

Nonlinear drug absorption can occur when the process is rate-limited by solubility, carrier-mediated transport systems, or saturation of the presystemic gut wall or hepatic metabolism. For instance, high doses of riboflavin...
