How are Electrical Signals Generated at the Nanoscale?
Electrical signals at the nanoscale are typically generated through the application of voltage across nanostructures. This can be achieved by using electrodes that are precisely positioned at the nanoscale. The interaction of these electrodes with nanoscale materials can create a flow of electrons, leading to the generation of electrical signals. Techniques such as scanning tunneling microscopy (STM) and atomic force microscopy (AFM) are often employed to manipulate and measure these signals with high precision.
