tin, used in making fusible alloys, in plating aircraft bearings and mirrors, and in compounds for making liquid crystal displays and transistors. Atomic number 49; atomic weight 114.82; melting point 156.60°C; boiling point 2,072°C; specific gravity 7.31; valence 1, 2, 3. SeePeriodic ...
number for indium is 49 and indium's symbol is In. It has an atomic mass of 114.818. The In element is in group 13 and period 5 on the periodic table, which means indium's electron configuration is atoms with five shells holding a total of about 49 electrons. Indium is apost-...
For at least part of this spectral range the experimental values agree with the Drude free electron formulae if the effective number of free electrons per atom, N0, and their relaxation time, , are treated as adjustable parameters. The values of N0 exceed the numbers of valence electrons per...

(i) A decrease in the number of electrons of Ni atoms compared to that of As ones leads to a decrease in Coulomb repulsion between electrons of In atoms in the scaffold and electrons of N and Ni atoms in the body of the molecules. (ii) Compared to that of As atoms, ELS of Ni ...
In this method a known number of charge carrier is induced in the conduction channel of a semiconductor and the corresponding increase of the current is measured. From this current increase the carrier mobility can directly be resolved. The structure used for this measurement consists of a silicon...
