Dear Users and Developplers,<br><br>I'm trying to calculate Bi2Te3 which belongs to space group 166, if I start from the rhombohedral structure, then after setting automatically RMT, the RMT for Bi1, Te1, Te2 atoms are larger than 2.0 and the initialization is totally fine (I hardly need to change default settings). However, if I use the hexagonal structure which is supposed to be equivalent to the rhombohedral one, after setting automatically RMT, the RMT for Bi1, Te1, Te2 atoms are 1.64, 0.86 and 0.86, then when I run the initialization, the nn is fine, however, x lstart is complaining for charge leakage for all atoms, even if I increase the separation energy to -10Ry, it still could not work. <br>
<br>Could you please give me some idea why this happens? Thanks a lot!<br clear="all"><br>Many thanks!<br>Bo<br>
