开量子环中电子波函数的成像
Imaging Electron Wave Functions Inside Open Quantum Rings
摘要:
结合扫描门显微镜(SGM)的实验和模拟,我们展示了嵌入介观量子环(QR)中的电子概率密度$|Ψ|^{2}(x,y)$的低温成像。尖端诱导的电导调制与Aharonov-Bohm效应具有相同的温度依赖性,表明它们起源于电子波函数干扰。$|Ψ|^{2}(x,y)$和SGM电导图的模拟再现了主要的实验观察结果,并将SGM图像中的条纹与$|Ψ|^{2}(x,y)$联系起来。
英文摘要:
Combining Scanning Gate Microscopy (SGM) experiments and simulations, we demonstrate low temperature imaging of electron probability density $|Ψ|^{2}(x,y)$ in embedded mesoscopic quantum rings (QRs). The tip-induced conductance modulations share the same temperature dependence as the Aharonov-Bohm effect, indicating that they originate from electron wavefunction interferences. Simulations of both $|Ψ|^{2}(x,y)$ and SGM conductance maps reproduce the main experimental observations and link fringes in SGM images to $|Ψ|^{2}(x,y)$.
