- W2074094328 abstract "X-ray photoelectron spectroscopy (XPS) and low-energy electron diffraction (LEED) have been used to examine the chemical composition of GaAs(100) surfaces after different standard cleaning sequences, using aqueous H2 SO4 :H2 O2/ HCl and H3 PO4 :H2 O2/ HCl solutions. XPS measurements show that the oxides, Ga2 O3 and As2 O3 , which remain at a relative concentration of 1.7:1 after H3 PO4 :H2 O2 :H2 O etch, are totally removed by the subsequent aqueous HCl solution. These same oxides, which have a relative concentration of 2.5:1 after H2 SO4 :H2 O2 : H2 O etch, are then not totally removed by HCl. Elemental arsenic was found to increase in concentration as the surface oxides decreased. The surface, initially gallium rich (Ga/As ratio 1.11), became arsenic rich (Ga/As ratio 0.93) after cleaning in HCl. The excess elemental As can be removed by subsequent treatment in NH4 OH. LEED patterns could be obtained only for H3 PO4 :H2 O2 /HCl cleaned surfaces. Au/Ti/GaAs Schottky diodes were made on both types of samples after cleaning. I–V measurements show that the diodes on the H3 PO4 :H2 O2/HCl cleaned surfaces have a better ideality factor (ranging from 1.15 to 1.20), than those on H2SO4 :H2 O2/HCl cleaned surfaces (ranging from 1.20 to 1.25), while the barrier heights are about the same for both (∼0.74 eV)." @default.
