Two-dimensional electron gases in low-pressure metalorganic vapour phase epitaxially grown InGaP homojunctions

We present modulation-doped ordered-InGaP/disordered-InGaP homojunctions grown, lattice matched to GaAs, by metalorganic vapour phase epitaxy. Capacitance—voltage (C—V) profiling techniques, temperature-dependent Hall, Shubnikov—De Haas and photoluminescence measurements have been used for characterization. The C—V measurements show a narrow profile at the homointerface with an order of magnitu...

The Development of a Column-Switching High-Performance Liquid Chromatograph System for Chiral Separation of Mouse Urinary D, L-Lactate

Two high-performance liquid chromatograph (HPLC) systems with a Rheodyne Model 7000 switching valve for separation of Dand L-lactate in biological samples has been reported. However, since the switching valve was rotated manually, so that only 10 samples could be determined within one day. For better efficiency, a circuit for rotating the switching valve automatically, which is including mechan...
