The name of the game is to produce diamond films at the lowest possible temperature.cheap oakley sport sunglasses black frame gray lensesfok202 fake If I can grow the films at degrees it makes it possible for me to integrate this material with a whole range of other semiconductor materials Sumant said.

By using a new technique that altered the deposition process of the diamond films Sumant and his colleagues at Argonnes Center for Nanoscale Materials were able to both reduce the temperature to close to degrees Celsius and to tune the thermal properties of the diamond ficheap oakley asian fit black frame fok305 fakelms by controlling their grain size This permitted the eventual combination of the diamond with two other important materials graphene and gallium nitride.

According to Sumant diamond has much better heat conduction properties than silicon or silicon oxide which were traditionally used for fabrication of graphene devices.discount oakley hijinx black frame020 fake As a result of better heat removal graphene devices fabricated on diamond can sustain much higher current densities.cheap oakley sunglasses white frame fakecheap oakley limited fok303 fake

In the other study Sumant used the same technology to combine diamond thin films with gallium nitride which is used extensively in high power light emitting devices After depositing a diamond film on a gallium nitride substrate Sumant and his colleagues noticed a considerable improvement in the thermal performance. Because a difference within an integrated circuit of just a few degrees can cause a noticeable change in performance he called this result remarkable
