摘要:
High quality monocrystalline metal oxide layers are grown on a monocrystalline substrate such as a silicon wafer. The monocrystalline metal oxide is grown on the silicon substrate at a temperature low enough to prevent deleterious and simultaneous oxidation of the silicon substrate. After a layer of 1-3 monolayers of the monocrystalline oxide is grown, the growth is stopped and the crystal quality of that layer is improved by a higher temperature anneal. Following the anneal, the thickness of the layer can be increased by restarting the low temperature growth. An amorphous silicon oxide layer can be grown at the interface between the monocrystalline metal oxide layer and the silicon substrate after the thickness of the monocrystalline oxide reaches a few monolayers.

摘要:
A power source (212) is disclosed for charging a battery (330) within a portable electronic device (310). An apparatus (422), such as a photovoltaic or thermoelectric cell, for charging the battery (330) is disposed contiguous to and within a transparent housing (412) of the portable electronic device (310). A fluorescent species (416), such as quantum dots or a fluorescent dye, is disposed on a side of the housing (412) opposed to the apparatus (422). Light (430) striking the fluorescent species (416) is converted into photons (432, 434) having a narrower spectrum that passes through the housing (412) to the apparatus (422). An optional layer (418) may be disposed on the fluorescent species (416) that reflects light from the fluorescent species (416) to the apparatus (422). Photonic crystals (415) may be combined with the fluorescent species (416) to increase reflectivity.
