O projekcie
CEL PROJEKTU:
Głównym celem projektu jest poszukiwanie nowych zjawisk fizycznych w układach o rozmiarach nanometrycznych, które wynikają z współistnienia i współoddziaływania prądu ładunkowego, prądu spinowego oraz prądu ciepła. W szczególności, przeprowadzone zostaną teoretyczne badania spinowych efektów w konwencjonalnej termoelektryczności oraz badania tzw. spinowych efektów termoelektrycznych. Badania te obejmą niskowymiarowe układy i układy hybrydowe, takie jak układy wielowarstwowe (metaliczne zawory spinowe, magnetyczne złącza tunelowe, układy nanokolumnowe), układy jedno-elektronowe (oparte na kwantowych kropkach, molekułach i atomach), dwuwymiarowe struktury, oraz magnetyczne kwantowe nanodruty. Istotnym elementem tych badań jest zaproponowanie nowych zjawisk fizycznych wraz z ich teoretycznym opisem i modelowaniem. Zrozumienie i wyjaśnienie zarówno nowych spinowych efektów, jak również niektórych zjawisk termoelektrycznych odkrytych ostatnio w układach nanoskopowych, będzie ważnym zadaniem projektu.
