Student thesis: Master's Thesis


The experiment include two parts First two dimensional Bi(111) bilayer (BL) are prepared on Bi2Se3 by hydrogen atom etching Secondly further deposit tin on Bi BL/Bi2Se3 to grow two dimensional stanene Scanning tunneling microscope (STM) and angle-resolved photoemission spectroscopy (ARPES) were used to analyze the etching mechanism and its band structure For Bi BL we observed the revolution process with varied hydrogen dosing by STM and eventually form a sigle bismuth (111) bilayer on Bi2Se3 Regarding stanene we successfully grew the stanene on BL/ Bi2Se3 the honeycomb structure observed by STM strongly support our finding
