AB  - Highly mobile 2-dimensional electron gases (2DEGs) at the (001), (011) and 
      (111)-oriented LaAlO(3)/SrTiO(3) (LAO/STO) interfaces are obtained using spin 
      coating chemical method, which is a gentle technique without plasma bombardment 
      of the pulsed laser deposition. As revealed by x-ray diffraction spectrum and 
      x-ray reflectivity analysis, the LAO over layer is epitaxially grown, and has a 
      uniform thickness of  approximately 15 nm,  approximately 20 nm and  approximately 26 nm for (001), (011) and (111) 
      orientations, respectively. The interfaces are well metallic down to 2 K. The 
      carrier mobilities are  approximately 28 000 cm(2) V(-1) s(-1),  approximately 22 000 cm(2) V(-1) s(-1) and 
       approximately 8300 cm(2) V(-1) s(-1) at 2 K for the (001), (011) and (111) LAO/STO interfaces, 
      respectively, and  approximately 8 cm(2) V(-1) s(-1),  approximately 4 cm(2) V(-1) s(-1) and  approximately 4 cm(2) V(-1) 
      s(-1) at room temperature. The present work shows that the spin coating chemical 
      method is a feasible approach to get high quality 2DEG at both the 
      polar/non-polar and polar/polar interfaces.
