Web10.4.7.1 Physical Principles. This popular thin-film characterization technique ( Ref. 41) relies on the use of very high energy (MeV) beams of low-mass ions. These have the property of penetrating thousands of angstroms or even microns deep into films or film/substrate combinations. Interestingly, such beams cause negligible sputtering of ... WebThe above eight measurements of Hall voltages V 24P, V 42P, V 13P, V 31P, V 24N, V 42N, V 13N, and V 31N determine the sample type (n or p) and the sheet carrier density ns. The Hall mobility can be determined from the sheet density ns and the sheet resistance RS obtained in the resistivity measurement. See Eq. (2).
