内容記述 | Optical absorption and photoluminescence spectra in the range 1.2–2.2 eV have been measured in free-standing films of porous Si under hydrostatic pressures up to 6.4 GPa at room temperature. The absorption rises nearly exponentially in the low energy region. Under pressure, the whole spectrum shifts toward lower energies with a pressure coefficient of about −90 meV/GPa. The photoluminescence spectrum also exhibits a redshift of about −40 meV/GPa. These results are interpreted by analogy with the pressure-induced shrinkage of the optical energy gap seen in amorphous chalcogenide semiconductors. | |||||
