Molding two-dimensional organic molecule crystals

Recently, a group of illegal counterfeiters was apprehended for producing around 400 fake luxury jewelry items using molds. They were able to create hundreds of faked luxury items simply after pouring molten metal into molds produced from the original jewelry. Similarly, in the molecular world, a template scaffold can produce an endless amount of molecular crystals of any shape or form.

2D material controls light twice stronger

E-Mail IMAGE: The SH light produced in the MoS2 double layer has the same phase as the MoS2 layer so the overlaid secondary harmonic wave has linear polarization. However, in a heterobilayer. view more Credit: POSTECH Since the invention of world s first laser - the ruby laser - in 1960, the human desire to control light has spread to various industries, including telecommunications, medicine, GPS, optical sensors and optical computers. Recently, a POSTECH research team has taken a step closer to its goal of controlling light by identifying nonlinear optical phenomena occurring in heterobilayers composed of two-dimensional materials. A nonlinear optical phenomenon refers to the occurrence of light whose intensity is not doubled when optical input intensity becomes doubled, in which the resulting output has different frequencies from original input. This phenomenon is easily understood if you think of electrons and nuclei as spring-connected oscillators. When the spri
