Smallest Transistor Ever
- cdvonstinkpot 10y agoOne thing FTA that I don't understand is when they say the electron passing through the MoS2 is heavier than an electron in silicon, aiding in controllability. As I understand, an electron is an electron is an electron in any substance, the only variable being the number of which are able to move as is determined by the valence ring. If someone with a better understanding than I could comment on this, I'd be grateful.

- cdvonstinkpot 10y agoThank you. This is all brand-new to me & I find it quite interesting. It took me a while to wrap my head around it though. This is how I understand it now- please correct me if I'm wrong. The electron tar ball 'weight' is determined by the amount of perturbation happening in those atoms as is determined by the material/substance in which those atoms exist. The electron tar ball is like the 'sum' of the bare electron's mass plus the effect of the perturbation in the surrounding environment, resulting in an effective 'weight', or influencing force of more than the bare electron's mass. If I understand correctly, the electron which is surrounded by additional atomic components can be ejected into a vacuum, & in this case will only be able to affect another anything based on its own mass, devoid of additional forces contributed by perturbation in the surrounding atom componentry- since it left its proximity to go into the vacuum.
