论文摘要
我们证明了经过修改以通过触觉装置控制的低温扫描探针显微镜（SPM），因此操作员可以“感觉到”正在研究的样品的表面。该系统允许对晶体的原子和顶部的原子进行直接触觉感觉，并通过使用不同的SPM模态来模拟代表控制SPM的相关原子力的感觉。特别是，我们以（1）常规STM反馈，（2）能量依赖性电子密度成像，（3）基于AFM频率和基于振幅的力传感的模式和（4）原子操纵/滑动。我们还使用软件将触觉反馈感觉修改为模仿不同的原子质力，包括共价键，库仑排斥，范德华瓦尔斯的排斥和全伦纳德·琼斯的潜力。 SPM控制的这种方式为基于人类的直觉扫描创造了新的机会，它也是一种新型的教育工具，可以帮助理解原子水平的材料。
We demonstrate a cryogenic scanned probe microscope (SPM) that has been modified to be controlled with a haptic device, such that the operator can `feel' the surface of a sample under investigation. This system allows for direct tactile sensation of the atoms in and on top of a crystal, and we simulate, by using different SPM modalities, a sensation that is representative of the relevant atomic forces controlling the SPM. In particular, we operate the microscope in modes of (1) conventional STM feedback, (2) energy-dependent electron density imaging, (3) q-plus AFM frequency and amplitude based force sensing, and (4) atomic manipulation/sliding. We also use software to modify the haptic feedback sensation to mimic different interatomic forces, including covalent bonding, Coulomb repulsion, Van der Waals repulsion and a full Leonard-Jones potential. This manner of SPM control creates new opportunities for human-based intuition scanning, and it also acts as a novel educational tool to aid in understanding materials at an atomic level.
