An analytical expression is derived for the energy of a three-component electron-hole liquid (EHL) in a magnetic field. Results of calculations of the EHL properties in Si/Si{sub 1–x}Ge{sub x}/Si quantum wells are presented. The influence of the magnetic field on the EHL properties and stability depending on the germanium concentration in the SiGe layer is revealed. It is found that the equilibrium electron-hole pair density strongly increases with the magnetic field. It is shown that the dependences of the filling factors of the Landau levels on the magnetic field are shaped as plateaus.
