“…In particular, there is a variety of perovskite metal oxides exhibiting such unique phenomena as colossal magnetoresistance [1,2], charge ordering [2], spin dependent transport [3], and formation of 2D electron gases [4] to name a few. In addition, perovskites are often mentioned as key materials in the advancement of photovoltaics [5,6], and are also incorporated in the development of applications in photonic devices [7,8], lasing media and LEDs [5,[9][10][11], fuel cell technology [12], memory devices [1,[13][14][15], catalytic chemistry, superconductivity [16][17][18], and much more.…”
