Abstract:
1. A top-emitting nitride-based light emitting device, comprising: an active layer between an n-type clad layer and a p-type clad layer: an interface modification layer formed on the p-type clad layer; and a transparent conductive thin film layer made up of a transparent conductive material formed on the interface modification layer, wherein the interface modification layer is formed of an alloy to which additional elements are added while containing indium as a main component, or a solid solution thereof, and wherein the additional elements added to indium for the interface modification layer include at least one selected from tin (Sn), zinc (Zn), gallium (Ga), cadmium (Cd), magnesium (Mg), beryllium (Be), silver (Ag), molybdenum (Mo), vanadium (V), copper (Cu), iridium (Ir), rhodium (Rh), ruthenium (Ru), tungsten (W), cobalt (Co), nickel (Ni), manganese (Mn), palladium (Pd), platinum (Pt) and lanthanum (La).
