Sphalerite crystal

We study nonlinear vibrational localized modes in one dimensional diatomic chain with different masses and alternating force constants between nearest neighbors by numerical calculation . This model simulates a row of atoms in the 〈 111 〉 direction of a sphalerite structure crystal .

利用数值计算研究近邻原子质量和作用力常数均不同的一维链中的非线性局域模，该模型模拟闪锌矿结构晶体中〈111〉方向一列原子的非线性振动。
