Researchers visualize the microscopic phases of magic-angle twisted bilayer graphene

Researchers from Princeton University, University of California, Japan's National Institute for Materials Science, CNRS and Lawrence Berkeley National Laboratory have use high-resolution scanning tunnelling microscopy to study the wavefunctions of the correlated phases in magic-angle twisted bilayer graphene (MATBG). 

For the first time, the researchers were able to specifically capture unprecedentedly precise visualizations of the microscopic behavior of interacting electrons that give rise to the insulating quantum phase of MATBG. Additionally, through the use of novel and innovative theoretical techniques, they were able to interpret and understand these behaviors.

Sparc Technologies reports positive results from testing of ecosparc-enhanced coatings

Sparc Technologies has reported positive results in relation to its ecosparc product. The critical Thermal-Cycling Resistance Testing has reportedly demonstrated significant reductions in cracking when utilizing ecosparc-enhanced coatings in comparison to coatings without ecosparc.

The prevention and postponement of cracking plays a pivotal role in extending the life of protective coatings. A primary cause of coating deterioration, which subsequently leads to corrosion and asset degradation, is the occurrence of cracks on welds and angular surfaces. An accredited third-party laboratory conducted the ThermalCycling Resistance Test.

In the coming decades, quantum technology is expected to provide various technological breakthroughs: smaller and more precise sensors, highly secure communication networks, and powerful computers that can help develop new drugs and materials, control financial markets, and predict the weather much faster than current computing technology ever could. To achieve this, there is a need so-called quantum materials: substances that exhibit pronounced quantum physical effects. One such material is graphene. Giving it a ribbon-like shape,  for example, gives rise to a range of controllable quantum effects.

Researchers develop new method for precise atomic-scale manufacturing using electron beams

Researchers at  Oak Ridge National Laboratory (ORNL) and Arizona State University have developed a technique that combines two approaches to nanofabrication - top-down and bottom-up methods - to enable atomic-scale precision manufacturing using a focused electron beam.

Top-down methods, such as lithography, employ external influences to modify materials. While they offer precision patterning, their resolution is often constrained by factors like beam size and scattering effects. On the other hand, bottom-up methods capitalize on the spontaneous self-assembly of atoms and molecules through chemical reactions, granting atomic-level control. However, the positioning in this method tends to be random rather than directed.
The novel technique demonstrated on twisted bilayer graphene (TBG) harmoniously integrates these two approaches.

Researchers develop method to program twist angles and strain profiles in 2D materials

Researchers from Columbia University, Technical University of Denmark, Aarhus University, Université Paris-Saclay and Japan's National Institute for Materials Science have designed a simple fabrication technique that could help study the fundamental properties of twisted layers of graphene and other 2D materials in a more systematic and reproducible way. The team used long “ribbons” of graphene, rather than square flakes, to create devices that offer a new level of predictability and control over both twist angle and strain.

Graphene devices have typically been assembled from atom-thin flakes of graphene that are just a few square millimeters. The resulting twist angle between the sheets is fixed in place, and the flakes can be tricky to layer together smoothly. “Imagine graphene as pieces of saran wrap—when you put two pieces together you get random little wrinkles and bubbles,” says Columbia postdoc Bjarke Jessen, a co-author on the paper. Those bubbles and wrinkles are akin to changes in the twist angle between the sheets and the physical strain that develops in between and can cause the material to buckle, bend, and pinch randomly. All these variations can yield new behaviors, but they have been difficult to control within and between devices.
