RE: Transistors hit a new benchmark for size

in #science • 8 years ago

The reason that it works is because the electrons that go through the silicon transistors are lighter and come into contact with less things that cause resistance. MoS2 on the other hand has heavier electrons and runs into a different sort of issue.

I do not understand that statement. The electron mass is 511 keV. That's it. There is not such things like lighter or heavier electrons. Could you please specify? I have found the same information on the source, and it is equally wrong ;)

Thanks in advance!

      Yes it does. Thanks. Actually, the electrons behave as if they where heavier. The 'as if' has is own importance in the sentence. Quantum effects yield them to get an effective mass that is heavier. This is different from the electron mass which is of course constant.

      PS: maybe could you consider updating slightly this paragraph of your post?
