The surface stability of single crystals Bi 2Se 3 and Bi 2Te 3 has been studied by XPS, AFM, STM and RHEED techniques. The Bi 2Se 3 and Bi 2Te 3 single crystals were grown by vertical Bridgman method. Crystal cleaving induced atomically flat surfaces over 1 cm 2 area. XPS revealed that cleaved Bi 2Se 3 and Bi 2Te 3 surface were stable to oxidation over two months. The surfaces are sufficiently inert to obtain STM atomic resolution even in two weeks after cleaved. © 2011 IEEE.
