Breakthrough in materials for actuators paves way to electronically integrated microscopic robots

Research

Fifty years of Moore’s Law scaling in microelectronics have brought remarkable opportunities for the rapidly-evolving field of microscopic robotics. Electronic, magnetic, and optical systems now offer an unprecedented combination of complexity, small size, and low cost, and could readily be appropriated to form the intelligent core of microscopic robots.

High-conductivity 2D holes induced by polarization discontinuity in GaN/AlN

Research

When an electrically-insulating material is grown on top of another insulator, the interface between the two insulators can be populated by mobile electrons. This has been achieved in interfaces that have a polarization discontinuity, such as AlGaN/GaN and LaAlO3/SrTiO3.

Biomimetic design of 3D-printed cartilege

Research

Cornell researchers employ advanced 3D printing technologies, along with bio-inspired design principles and multiscale predictive modeling to optimize the chemo-mechanical properties of bioprinted artificial cartilage.

Maximizing the spin Hall effect by tuning crystal structure

Research

Cornell scientists have found that thin films of SrRuO3, when optimally produced, have an exceptionally high spin Hall ratio. This is directly correlated with the degree that octahedral RuO6 subunits in the crystal are tilted away from a flat in-plane orientation.

Teaching and Inspiring Students in Puerto Rico

Education

Graduate student Omar Padilla Velez, an NSF Graduate Research Fellow, gathered a team of Cornell scientists working in fields from Chemistry to Physics, to bring science to students from middle to undergraduate schools in Puerto Rico.

Three-Atom Thick Fabrics Made by Seamless Stitching of Single-Layer Crystals

Research

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.

Using Math to Search for a 'Needle in a Haystack' to Make Better Solar Cells

Research

CCMR researchers have used mathematical methods, typically used in business forecasting, to suggest which combination of components will make the best solar cell materials in a “perovskite” arrangement. These materials are made in solution, essentially in a beaker, at room temperature. This makes them far more energy-conservative than traditional silicon solar cells.

Threading Atom-Wide Wires Into 2D Materials

Cornell University researchers and collaborators have discovered – somewhat accidentally – a method for inserting a one-dimensional (1D) semiconductor channel into the “fabric” of a material that is only a few atoms thick.

Through the Atomic Scale Looking Glass

Research

In Through the Looking Glass, Alice steps through a mirror into a world in which everything is its mirror image. Realizing that writing in books is reversed, Alice wonders what has happened on the atomic scale.

Simple stretch “flips” the sign of charge carriers

Research

Electricity is the flow of charged particles through a material, such as a wire — a process that resembles a river of water molecules flowing through a canyon. But are the charged particles positive or negative?
