Summary
Přednáška je závěrečnou částí základního kurzu fyziky. V jejím úvodu je objasněna historická geneze pojmu „nanostruktura“ a je formulováno zdůvodnění terminologické hranice 100 nm na základě centrálního limitního teorému statistické fyziky. Následující přednášky jsou věnovány deseti nejznámějším jevům z oblasti nanověd včetně základů kvantové teorie pásové struktury elektronových hladin pod vlivem kvantové restrikce. V teoretických cvičeních jsou úlohy voleny tak, aby jejich zpracování přispělo k pochopení jevů probíraných na přednáškách Základy Fyziky Nanostruktur.
