I would not call it the energy required to create and electron-hole pair since as everybody knows the absoprtion of a 1.12eV can lead to the generation of an electron-hole pair.<br />This 3.6eV energy is generally described as the empirical ratio between the total energy deposited in the considered silicon volume by a high energy photon (start to be valid for X-rays, and possibly some EUV photons I guess) to the number of effectively generated electron hole pairs (after relaxation of the primary generated electrons, i.e. the effective number of free carriers you get a significant time after the interaction).<br />So its an average energy per effectively created electron hole pair when a high energy photon is absorbed in the silicon (and thus when a large number of electron-hole pairs are created localy). As far as I remember it includes many physical mechanisms of energy loss (phonon interactions but also electron-electron interactions and many more).<br />I don't think it applies to visible photons and I think the following comment is misleading (and most likely wrong): "This is due to the phonon excitation, which is required for momentum conservation"Vincent Goiffonhttps://www.blogger.com/profile/03481165633618218395noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-6704150982553121592016-12-13T12:22:25.827+02:002016-12-13T12:22:25.827+02:00Has a MIGFET image sensor ever been produced or de...Has a MIGFET image sensor ever been produced or demoed?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-31656134270251169272016-12-13T10:12:46.414+02:002016-12-13T10:12:46.414+02:00But every coin has two sides, also here is some go...But every coin has two sides, also here is some good news to find : there remains a need for training in the field of solid-state imaging, even for the fundamental physics of it !Albert Theuwissennoreply@blogger.com
