It consists of a layer of cadmium sulfide a semiconductor that is laid on top of a sheet of silver with a layer of magnesium fluoride in the middle.
or zinc sulfide at the scorching temperatures of 450 degrees Fahrenheit found on GJ 1214b. ou would expect very different kinds of clouds to form than you would expect say on Earthkreidberg says.
and earth-abundant elements unlike compound semiconductor materials currently used in efficient thin-film solar cell technology. he research was supported by the Energy Commercialization Institute of Ben Franklin Technology Partners the Department of energy's Office of Basic Sciences
"A nonlinear material, such a cadmium sulfide, can change the frequency, and thus the color, of light that passes through it,
the researchers needed a way to amplify the intensity of a light wave as it passed through a cadmium sulfide nanowire.
so that light is contained mostly within the cadmium sulfide rather than at the interface between it and the silver shell,
"The frequency-changing efficiency of cadmium sulfide is intrinsic to the material, but it depends on the volume of the material the wave passes through,
On the other hand, what are known as compound semiconductors are to be embedded into conventional materials. In contrast to silicon, many of such semiconductors with extremely high electron mobility could improve performance of the most modern silicon-based CMOS technology.
they integrated compound semiconductor crystals made of indium arsenide (Inas) into silicon nanowires, which are suited ideally for constructing increasingly compact chips.
"In the next step, the scientists want to implement different compound semiconductors into Silicon nanowires and also optimize the size and distribution of the crystals a
It consists of a layer of cadmium sulfide, a semiconductor, laid on top of a sheet of silver with a layer of magnesium fluoride in the middle.
and cadmium sulfide (Cds) shells that increase the Stokes shift while reducing photon re-absorption, says Bronstein.
monolithic approach Previous efforts to combine the efficiency of compound semiconductor lasing structures with the scalability of a silicon substrate have focused largely on flip-chipping of prefabricated diodes,
and compound semiconductors is to grow a so-called buffer layer on top of the silicon. But for the particularly large mismatch of Inp and silicon,
That approach would allow deposition of the compound semiconductor materials needed to red-shift the lasing wavelength into the telecoms realm at 1300 nm.
though other materials such as cadmium sulfide and cadmium selenide also are used for emitting visible colors. The main challenge, the researchers noted, lies in the way light emitting semiconductor materials are grown
and cadmium sulfide to provide a route to low-cost, scalable and green synthesis of Cds nanocrystals with extrinsic crystallite size control in the quantum confinement range.
Researchers from the IBM Materials Integration and Nanoscale Devices group demonstrated a novel, robust and yet versatile approach for integrating III-V compound semiconductor crystals on silicon wafers a novel and an important step

but the new method is the key to integrating the technology with silicon platforms. hat sets this work apart from other methods is that the compound semiconductor does not contain detrimental defects,
