  1. 1. CVD and ALD in the Bi-Ti-O system

    Författare :Mikael Schuisky; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Halide-CVD; ALD; Bismuth titanate; Bi4Ti3O12; Titanium oxide; TiO2; Bismuthoxide; Bi2O2.33; Epitaxy; QCM.; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Bismuth titanate Bi4Ti3O12, is one of the bismuth based layered ferroelectric materials that is a candidate for replacing the lead based ferroelectric materials in for instance non-volatile ferroelectric random access memories (FRAM). This is due to the fact that the bismuth based ferroelectrics consists of pseudo perovskite units sandwiched in between bismuth oxide layers, which gives them a better fatigue nature. LÄS MER
