Webb5 aug. 2015 · It is interesting to observe large peak shift for E g 2 and A 1g 2 modes (>25 cm −1) while the chemical composition is changed from Bi 2 Te 2 Se to Bi 2 TeSe 2. In comparison, the position of A 1g 1 mode does not have significant shift for the reason that the out-of-plane stretching is not so sensitive to the change of chemical bonds.
