In collaboration with the Chicago Museum of Science and Industry, HerStory is an outreach event that encourages young girls, particularly underrepresented minorities, to pursue science in academia and beyond. The event agenda includes a massive scavenger hunt at the museum that featured exhibits of famous female scientists in each wing of the museum.
Two-dimensional (2D) layered materials have many features suitable for optoelectronic devices, but poor quality substrates can degrade optical properties. By encapsulating a monolayer semiconductor in layers of atomically-thin hexagonal boron nitride, a nearly pristine environment can be achieved free from surface roughness and defects of typical substrates.
A new strategy has been introduced to exploit mechanical buckling for autonomic origami assembly of three-dimensional (3D) microstructures across a wide range of material classes, including soft polymers and brittle inorganic semiconductors, and length scales from nanometers to centimeters.
Recent advances in gold nanoparticle synthesis combined with functionalization with DNA linkers has enabled the self-assembly of stacks of gold nanodisks in which the optical spectra can be tuned and modulated by controlling the stack structure (e.g., particle spacing, arrangement, and stack length).
At the nanometer-scale, the surface area to volume ratio increases substantially compared to bulk materials. Consequently, methods for functionalizing and passivating surfaces can play a dominant role in determining the properties of nanomaterials.
Due to their outstanding electronic properties and high optical transparency, metal oxide thin-film transistors have significant potential in state-of-the-art flat panel display technologies.
Amorphous oxide semiconductors commonly are indium oxides doped with other metal ions. Although it is known that the introduction of secondary metal ions decreases the degree of crystallinity and elevates the crystallization temperature, there is a lack of systematic study to compare and quantify the effects of different dopant elements.
Atomically thin two-dimensional (2D) materials exhibit superlative properties dictated by their intralayer atomic structure, which is typically derived from a limited number of thermodynamically stable bulk layered crystals (e.g., graphene from graphite).
Dielectric materials play a critical role in determining the operating voltage in modern-day electronics. In particular, highly polarizable and ultrathin dielectrics enable low operating voltages and thus low power consumption.
Joining different materials can lead to all kinds of breakthroughs. In electronics, this produces heterojunctions — the most fundamental components in solar cells and computer chips. The smoother the seam between two materials, the better the electronic devices will function.
