Atomic number (Z) Integer equal to the number of protons in a nucleus; the order of an element in the periodic table. Atomic weight or nuclear mass number (A) An integer equal to the sum of the number of protons Z and neutrons N. Isobar Member of a set of nuclides of the same at...
The number of protons contained in the nucleus of an atom is called the atomic number ( Z ) and the number of neutrons is the neutron number ( N ). Because the masses of these particles are each approximately equal to one mass unit, the total number of protons plus neutrons is called ...
Therefore, the lattice stress generated by ion doping is the key contributor to the number of NRs. Interestingly, well-defined single NRs (sSMO NRs) can be harvested by fine tuning the amount of sulfur doping. The typical conformation of the sSMO NRs are shown in Fig. 3a, revealing free...
