Pure germanium may be converted into an N-type semiconductor by doping it with any donor impurity having 5 valence electrons in its outer shell. Since this type of semiconductor (N-type) has a surplus of electrons, the electrons are considered MAJORITY carriers, while the holes, being few in number, are the MINORITY carriers.

Reducing Interfacial Resistance between Garnet

Among all solid electrolyte materials ranging from sulfides to oxides and oxynitrides, cubic garnet–type Li 7 La 3 Zr 2 O 12 (LLZO) ceramic electrolytes are superior candidates because of their high ionic conductivity (10 -3 to 10 -4 S/cm) and good stability against Li metal.
