Nonstationary exclusion and accumulation of nonequilibrium charge carriers in germanium p⁺ -p-p⁺ structures of different geometrical forms

Kletski S. V., Piotrowski T., Sikorski S.

Electron Technology

1999

Vol. 32, No. 4

361-364

The mathematical model described non stationary exclusion and accumulation of nonequilibrium carriers of charge in structures of different geometrical from (parallelepiped, hollow cylinder and sphere) is developed and a comparative analysis of transient processes in these structures is provided. The nonstationary distributions of carriers concentration, electric field and voltage drop over the base of such kind structures are calculated. The dynamics of transient processes is discussed.

Comparative analysis and simulation of exclusion and accumulation of nonequilibrium charge carriers in p⁺ -p-p⁺ Ge structures of different geometrical forms

Kletski S. V., Pułtorak J., Sikorski S.

Electron Technology

1998

Vol. 31, No. 2

275-278

A mathematical model describing the processes of exclussion and accumulation of nonequilibrium charge carries in structures of different geometrical forms ( a parallelepiped, a tube and a hollow sphere ) is developed and a comparative analysis of the properties of these structures is provided. Carrier distributions and the electric field in the base of these structures are calculated, as well as current-voltage characteristics which are then corresponding experimental data. The possibility to obtain the needed characteristics through the selection of geometrical form of the sample is demonstrated.
