| Description | I. AFM in not accurate method for determination the surface termination of SrTiO3 substrates The TiO2 termination of the SrTiO3 substrates is critically important for fabrication of 2 DEG interfaces. Therefore we investigated the terminating layer (i.e. SrO or TiO2) of both commercially prepared and in house prepared TiO2-terminated substrates using LEIS. The results showed that, the actual termination was not 100% TiO2, despite AFM images suggesting a complete TiO2 terminated surface. II. A method was developed for reproducible fabrication on LaAlO3/SrTiO3 2DEG interface structures. The performed Transport measurements confirmed the carrier density and mobility at the interface are comparable to the previously published high quality samples. III. Memristive switching effect was observed in the current - voltage characteristics of thin LaAlO3 films grown on STO substrates. IV. Nano SQUID structures have been fabricated on top of the LaAlO3/SrTiO3 2DEG interface structures. |
