Jan Grahn

Professor vid Terahertz- och millimetervågsteknik

Jag forskar om lågbrusiga halvledarkomponenter. Min drivkraft är att bryta nuvarande känslighetsgräns för transistorbaserade förstärkare i mikrovågs- och millimetervågsområdet.

Min forskargrupp har demonstrerat transistorer med en brusnivå bara några gånger över gränsen för kvantbruset. Komponenten är en högelektron-mobilitetstransistor med en InAlAs-InGaAs heteroövergång. Vår forskning omfattar materialvetenskap, transistorteknologi, komponentfysik, elektrisk modellering, mikrovågsförstärkardesign och högfrekvensmätningar.

Våra resultat får genomslag hos kvantdatorer, radioastronomi och klimatsatelliter. Från vår grupp har företaget Low Noise Factory AB bildats vilket nu levererar förstärkarprodukter till nästan varenda kvantgrupp över hela världen.

Jag undervisar Elektriska Kretsar och System på Teknisk Fysik. Jag ger också en doktorandkurs om Höghastighetstransistorer vartannat år.
