The first experimental demonstration of a controllable rotating molecule gear is presented. A scanning tunneling microscope (STM) is used to construct, manipulate, and observe the rotation of the molecule gear. The appropriate combination of molecule design, molecule manipulation protocol, and surface atomic structure selection leads to the functio...

... SEM image of the smallest solid state gear ever nanofabricated on a graphite surface with a diameter below 30nm in diameter for a thickness of 15 nm. Figure 6 shows an example of manipulation of such nanogear on the graphite substrate. This was obtained in an AFM tapping mode by mounting the graphite substrate on a movable piezo table. ...
Context 2
... AFM tip apex was fixed in x and y during the manipulation sequence and the piezo table moved step by step toward the tar-geted position on the graphite surface. A train of gears of different sizes can be assembled this way and AFM imaged afterward (see Figure 6a). An SEM image can be also recorded at the same location to appreciate the exact entanglement of the teeth between the nanogears of the train since this cannot be determined using the AFM images even in a taping mode (See Figure 6b). ...

An SEM image can be also recorded at the same location to appreciate the exact entanglement of the teeth between the nanogears of the train since this cannot be determined using the AFM images even in a taping mode (See Figure 6b). The step edges on the graphite substrate can be clearly resolved by the AFM in taping mode of opera- tion. ...

As semiconductor electronics keep shrinking, functionality depends on individual atomic scale surface and interface features that may change as voltages are applied. In this work we demonstrate a novel device platform that allows scanning tunneling microscopy (STM) imaging with atomic scale resolution across a device simultaneously with full electr...

This chapter focuses on Internet of Things from the nanoscale point of view. The chapter starts with section 1 which provides an introduction of nanothings and nanotechnologies. The nanoscale communication paradigms and the different approaches are discussed for nanodevices development. Nanodevice characteristics are discussed and the architecture of wireless nanodevices are outlined. Section 2 describes Internet of NanoThing(IoNT), its network architecture, and the challenges of nanoscale communication which is essential for enabling IoNT. Section 3 gives some practical applications of IoNT. The internet of Bio-NanoThing (IoBNT) and relevant biomedical applications are discussed. Other Applications such as military, industrial, and environmental applications are also outlined.
