Aquesta tesi tracta el desenvolupament de detectors de silici de tecnologia avançada per experiments de Física d'Altes Energies (HEP en anglès). La mida dels detectors de silici per determinar traces en experiments de HEP ha de disminuïr per millorar la resolució espacial en les mesures i millorar l'ocupancia en l'electrònica. Els experiments al CERN hauran de funcionar amb fluencies de fins a 2·10 16 n eq 1cm2 , i els detectors de silici més petits tindran menys atrapament de les parelles electró-forat generats al volum, que porta a un millor comportament sota un medi amb alts nivells de radi

Abstract:

Building complex quantum systems has the potential to reveal phenomena that cannot be studied using classical simulation. Photonics has proven to be an effective test-bed for the investigation of such quantum-enhanced technologies, however, the proliferation of bulk optical components is unlikely to be a scalable route towards building more complex devices. Instead, the miniaturisation, inherent phase stability and trivial alignment afforded by integrated photonic systems has been shown to be a promising alternative.
