| 内容記述 | The structural and optical properties of porous GaP have been studied by scanning electron\nmicroscopy, spectroscopic ellipsometry, and photoluminescence (PL) spectroscopy. Porous GaP\nlayers were fabricated by anodic etching in HF:H2O:C2H5OH=1:1:2 electrolyte on n-type (100)\nand (111)A substrates. The morphology of the porous GaP layer is found to depend strongly on the\nsurface orientation. Apart from the red emission band at ～1.7 eV, a supra-band-gap (EgX) emission\nhas been clearly observed on the porous GaP (111)A sample. The anodic porous layer on the (100)\nsubstrate, on the other hand, has shown only the red emission at 300 K and both red and green\ndonor-acceptor pair emissions at low temperatures. The correlation between the PL properties and\nthe porous morphology is discussed. An optical transition model is also proposed for the explanation\nof the PL emission properties of the porous GaP samples. | |||||
