Electronic states in semiconductor double quantum dots and quantum rings - Theory and tight-binding modeling
I detta examensarbete skapas en teoretisk modell av en dubbelkvantprick med särskilda egenskaper i programmeringspråket Python. Kvantprickar har ett brett användningsområde i bland annat LEDs och i lasrar men inte minst som beräkningsenhet i kvantdatorer.In recent experiments on semiconductor nanowires and quantum dots, enhanced g-factors up to several times the bulk value have been measured [1] [2]. The enhancement is attributed to orbital contributions g∗orb to the effective g-factor g∗ = g∗spin+g∗orb from the coupling of the high angular momentum ring-like states to the magnetic field. The objective of the work presented here is to model the do
