What is the mass of an electron in AMU? What is the atomic mass of fluorine? How many protons are in an isotope of sodium with a mass number of 25? What is the atomic mass of iron? What is dubnium's atomic mass? What is the difference between atomic number and mass number of an...
The effective mass of electrons at the Fermi level is found to be too small compared with the free electron mass and highly anisotropic. The low effective mass of conduction electrons indicates their high mobility and, hence, high conductivity of the boron sheet. Recently, we introduced [135] ...
