从理论上研究了T3晶格中的载流子在非均匀磁场和电场构成的磁电势阱中的约束。利用磁电组合势阱中电势可调的特点，靠增加电势阱深度从而增加粒子的束缚态数，或者增加势阱区域的宽度来改变束缚态数。利用磁电势阱构成电子波导或者量子线，计算了波导的本征模和概率流密度，指出了T3晶格的磁电波导可成为有希望的纳米电子器件。

The confinement of Dirac particles have been investigated theoretically where potential well with electric and inhomogeneous magnetic fields is perpendicularly to the T3 lattice plane .It has showed that the bound states number can be tuned by the potential well which dependence on depth and width of the potential well .The electronic waveguide or quantum wire can be formed by magnetic and electric potential well .The eigenmods and probability current densities are calculated in the T3 lattice waveguide .We hope that these characteristics can provide potential applications in the nano -material waveguide devices .
