We have performed angle-resolved photoemission spectroscopy on Tl_0.5_Bi_2_Te_3_ (TBT), a possible topological superconductor (TSC) derived from prototypical topological insulator Bi_2_Te_3_. We found that Fermi surface consists of multiple three-dimensional hole pockets surrounding the Z point, unlike another well-known topological-superconductor candidate Cu_x_Bi_2_Se_3. We also found that surface state can be controlled by surface-aging technique, making TBT an excellent platform to realize 2D TSC.
