Thickness-dependent transport channels in topological insulator Bi2Se3 thin films grown by magnetron sputtering
We study the low-temperature transport properties of Bi2Se3 thin films grown by magnetron sputtering. A positive magnetoresistance resulting from the weak antilocalization (WAL) effect is observed at low temperatures. The observed WAL effect is two dimensional in nature. Applying the Hikami-Larkin-Nagaoka theory, we have obtained the dephasing length. It is found that the temperature dependence...

متن کاملOrdered growth of topological insulator Bi2Se3 thin films on dielectric amorphous SiO2 by MBE.
Topological insulators (TIs) are exotic materials which have topologically protected states on the surface due to strong spin-orbit coupling. However, a lack of ordered growth of TI thin films on amorphous dielectrics and/or insulators presents a challenge for applications of TI-junctions. We report the growth of topological insulator Bi2Se3 thin films on amorphous SiO2 by molecular beam epitax...

Figure 1 . −K band structure evolution with T Si : a) 560 K (DP = 0.34 eV), b) 580 K (DP = 0.27 eV), c) 600 K (DP = 0.23 eV), d) 625 K (DP = 0.14 eV), and e) 630 K (DP = 0.12 eV). Upper panels show the ARPES intensity maps and lower panels show the corresponding MDC, measured at an interval of 10 meV. Red, purple, and green curves mark E F , VBM, and conduction band minimum (CBM), respectively....
متن کاملQuantized friction across ionic liquid thin films.
Ionic liquids - salts in the liquid state under ambient conditions - are of great interest as precision lubricants. Ionic liquids form layered structures at surfaces, yet it is not clear how this nano-structure relates to their lubrication properties. We measured the friction force between atomically smooth solid surfaces across ionic liquid films of controlled thickness in terms of the number ...
