Orientational tuning of the Fermi sea of confined electrons at the SrTiO3 (110) and (111) surfaces

T. C. Rödel, C. Bareille, F. Fortuna +9

We report the existence of confined electronic states at the (110) and (111) surfaces of SrTiO3. Using angle-resolved photoemission spectroscopy, we find that the corresponding Fer…
