The discussion revolves around the relationship between temperature tolerance and frequency tuning in wide bandgap semiconductors. Participants explore why materials with wider bandgaps exhibit higher temperature tolerance and how this characteristic may relate to the ability to achieve higher operational frequencies. The conversation includes requests for formulas and technical explanations.
Participants express uncertainty about the relationship between bandgap size, temperature tolerance, and frequency tuning. Multiple viewpoints are presented, but no consensus is reached on the specifics of these relationships or the formulas involved.
Participants do not provide specific formulas or detailed mathematical relationships, and there is a lack of clarity regarding the definitions of terms such as "thermal coefficient" in relation to silicon and other semiconductors.
well silicon are currently used in most integrated devices due to its high thermal properties. i was wondering if the thermal coefficient of semiconductors were higher than that of silicon would that mean it would be able to achieve higher frequencies due to its wider bandgap?gckaufman said:I don't know any formulas offhand but I can tell you that if the bandgap is larger, then it is harder to thermally excite electrons from the valence band to the conduction band. I don't know how that relates to frequencies though.
