Poster summary

Calcium aluminate Ca12Al14O33 (C12A7) referred as mayenite is the one of the mostly studying inorganic compounds in recent years. The mayenite electride (C12A7:e-) has high electron mobility, low work function (2.9 eV) and resistive switching properties. It is of special interest for micro- and nanoelectronic applications, so it is necessary to develop different techniques of fabricating C12A7 thin films. Depositing mayenite thin films often results to the formation of amorphous films requiring additional heating treatment. In this study we have investigated the features of a-C12A7 formation and its crystallization.
