According to classical physics, an electric current cannot flow in a circuit interrupted by an insulating barrier—that is, when electrons reach the “wall” of insulating material, they cannot continue forward. Since the 1930s, quantum theory had predicted that electrons might be able to “tunnel” through an insulating barrier if it were thin enough. Giaever discovered that cooling two semiconductors to near-absolute zero temperatures greatly enhances superconductivity. As a result of these studies, he developed a technique that allowed physicists to easily observe and measure semiconductor properties. This technique allowed Giaever to confirm certain previously unproven theories about superconductivity.

   Extractions: Giaever vystudoval elektroinženýrství na Norské vysoké škole technické v Trondheimu v roce 1952. V roce 1954 se pøestìhoval do Kanady, kde paracoval v Ontariu jako strojní inženýr ve spoleènosti General Electric Company. V roce 1956 byl pøesunut do centra spooleènosti v Schenectady (stát New Yoerk, USA). Zde se zaèal zabývat fyzikou, PhD získal v roce 1964 na Polytechnice v Troy (New York). I. Giaever svými pracemi navázal na práce L.Esakiho , který experimentálnì objevil tunelový jev. Propojil fyziku pevných látek se supravodivostí. Experimentálnì zkoumal tunelování elektronù mezerami v pevných látkách. Na vrstveném materiálu z normálního a supravodivého kovu dosáhl nových efektù tunelování a podpoøil BCS teorii supravodivosti (BCS = Bardeen Cooper Schrieffer ). Na práce Giaevereho navázal dále

In seguito venne mandato da quest’azienda negli Stati Uniti, dove si occup² di matematica applicata e di fisica dello stato solido . Riprese gli studi, laureandosi in fisica nel 1964, anno in cui divenne cittadino degli Stati Uniti. Le sue ricerche sull’effetto tunnel ebbero inizio poco dopo. L’effetto tunnel ¨ un fenomeno previsto dalla meccanica quantistica secondo il quale le particelle dotate di una certa energia hanno comunque una probabilit  non nulla di attraversare una regione ritenuta energeticamente inaccessibile dal punto di vista della fisica classica (barriera di potenziale).
