Si Nanocrystals for nanoelectronic applications


Si Nanocrystals for nanoelectronic applications

Zacharias, M.; Gösele, U.

First experimental results more than one decade ago demonstrated the visible room temperature luminescence of Si nanocrystals in implanted SiO2 or porous Si which triggered the strong interest in Si nanocrystal based systems and their properties. Basic fundamental questions concerning quantum confinement effects in indirect semiconductors as well as potential applications such as light emission from electrically excited Si nanocrystals, energy transfer to Er 3+ ions, and non volatile Si NC based memories also stimulated the broad scientific interest in this material system. For clarifying the origin of the observed luminescence signal as well as for applications, tight control over the size of the nanocrystals is essential. The talk will give an overview about ways for size controlled Si nanocrystals. Basic properties as well as various applications including memory applications will be discussed in details.
