drug profits to enrich their criminal organizations. A new approach that allows objects to become “invisible” has now been applied to an entirely different area: letting particles “hide” from passing electrons, which could lead to more efficient thermoelectric devices and new kinds of electronics.The concept — developed by MIT graduate student Bolin Liao, former postdoc Mona Zebarjadi (now an assistant professor at Rutgers University), research scientist Keivan Esfarjani, and mechanical engineering professor Gang Chen — is described in a paper in the journal Physical Review Letters.Normally, electrons travel

through a material in a way that is similar to the

motion of electromagnetic waves, including light; their behavior can be described by wave equations. That led the MIT researchers to the idea of harnessing the cloaking mechanisms developed to shield objects from view — but applying it to the movement of electrons, which is key to electronic and thermoelectric devices.Previous work on cloaking objects from view has relied on so-called metamaterials made of artificial materials with unusual properties.
The composite structures used for cloaking cause light beams to bend around an object and then meet on the other side, resuming their original path — making the object appear invisible. “We were inspired by this idea,” says

Chen, the Carl Richard Soderberg Professor of Power Engineering at MIT, who decided to study how it might apply to electrons instead of light. But in the new electron-cloaking material developed by Chen and his colleagues, the process is slightly different.
The MIT researchers modeled nanoparticles with a core of one material clickbank pirate review shell of another.
But in this case, rather than bending around the object, the

electrons do actually pass through the particles: Their paths are bent first one way, then back again, so they return to the same trajectory they began with.In computer simulations, the concept appears to work, Liao says. Now, the team will try to build actual devices to see whether they perform as expected. “This was a first

step, a theoretical proposal,” Liao says. “We want to carry on further research on how to make some real devices out of this strategy.”While the initial concept was developed using

particles embedded in a normal semiconductor substrate, the MIT researchers would like to see if the results can be replicated with other materials, such as two-dimensional sheets of graphene, which might offer interesting additional properties.The MIT

researchers’ initial impetus was to optimize the materials used in thermoelectric devices, which produce an electrical current from a temperature gradient. Such devices require a combination of characteristics that are hard to obtain: high electrical conductivity (so the generated current can flow freely), but low thermal conductivity (to maintain a temperature gradient).
But the two types of conductivity tend to coexist, so few materials offer these contradictory characteristics.
The team’s simulations show this electron-cloaking material

could meet these requirements unusually well.The simulations

used particles a few nanometers in size, matching the wavelength of flowing electrons and improving the flow of electrons at particular energy levels by orders of magnitude compared to traditional doping strategies. This might lead to more efficient filters or sensors, the researchers say. aquaponics 4 you download components on computer chips get smaller, Chen says, “we have to come up with strategies to control electron transport,” and this might be one useful approach.The concept could also lead to a new kind of switches for electronic devices, Chen says.
The switch could operate by toggling between transparent and opaque to electrons, thus turning a flow of them on and off. “We’re really just at the beginning,” he says.
“We’re not sure how far this is going to go yet, but there is some potential” for significant applications.Xiang Zhang, a professor of mechanical engineering at the University of California at Berkeley who was not involved in this research, says “this is very exciting work” that expands the concept of cloaking to the domain of electrons. The authors, he says, “uncovered a very interesting approach that may be very useful to thermoelectric applications.”This research was funded by the U.S. Department of Energy (DOE) through MIT’s Solid-State Solar-Thermal Energy Conversion center, a DOE Energy Frontier Research Center.
