Recently, we also demonstrated the existence of a bandgap guidance in topology whose diameter is smaller than the wavelength and the index of refraction may be higher than the elements of the photonic structure. |
Microstrip transmission lines with an electromagnetic bandgap structure exhibit stopband and slow-wave characteristics, which can be used as stop band or low-pass filters. |
Its wide bandgap, high electron mobility, high saturation and peak electron drift velocity, and high breakdown voltage, make it an ideal material for high power, high frequency electronic devices. |
The structure, morphology, electrical resistivity, optical bandgap, as well as thermal stability of the deposited films are investigated. |
Gallium nitride is a wide bandgap, compound semiconductor, with a number of inherent material properties that make it very attractive for designing and manufacturing high performance, robust, electronic components. |
Several research groups are investigating ways to create a bandgap in graphene, says Dr Hill. |
