The synthesis of CdTe nanocrystals (NCs) is performed by electrochemical deposition into prepared ion tracks in a a‐SiO₂/Si‐n template. As a result, CdTe NCs are obtained in a wurtzite (WZ) crystal phase. The measurement of the current–voltage characteristics shows that the CdTe (WZ NC)/SiO₂/Si system obtained in this way has n‐type conductivity. Computer simulations using the CRYSTAL computer code show good agreement between experimental and calculated lattice parameters. The theoretical calculations also show that the crystal has a direct bandgap at the Γ point of the Brillouin zone.

SiO2 / Si离子轨迹模板中CdTe纳米晶体的合成：电子和结构性质的研究

CdTe纳米晶体（NCs）的合成是通过电化学沉积到aa-SiO ₂ / Si-n模板中准备好的离子轨道中进行的。结果，在纤锌矿（WZ）晶相中获得了CdTe NCs。电流-电压特性的测量结果表明，以这种方式获得的CdTe（WZ NC）/ SiO ₂ / Si系统具有n型电导率。使用CRYSTAL计算机代码进行的计算机仿真表明，实验参数和计算出的晶格参数之间具有良好的一致性。理论计算还表明，该晶体在布里渊区的Γ点具有直接带隙。
