摘要
量子点是一种半导体纳米粒子，电子的运动被限制在纳米粒子的三个物理维度内，从而观察到能级的离散化。本文在液体中通过脉冲激光烧蚀成功合成了尺寸约为 9 ± 2 nm、能带隙约为∼ 2.8 eV 的 Bi2Te3 量子点。研究发现，这些点处于强约束状态。
Synthesis of strongly confined Bi2Te3 quantum dots by pulsed laser ablation in liquids
Quantum dots are semiconductor nanoparticles where electrons’ motion is confined within the three physical dimensions of the nanoparticle, such that discretization of energy levels is observed. In this article, quantum dots of Bi2Te3, with sizes around 9 ± 2 nm and energy bandgap around ∼ 2.8 eV, were successfully synthesized by pulsed laser ablation in liquids. Those dots were found to be within the strong confinement regime.
