Title: Algainp based light emission device
Inventor: NOTO NOBUHIKO
IPC: H01L33/14

Abstract: PURPOSE: To realize a good lattice matching by forming a current diffusion layer of an AlGaAsP layer having a direct band gap higher than the energy of photon radiated from the active layer at an emission layer part and a GaAsP layer formed thereon. CONSTITUTION: Since Alw Ga1-w As1-u Pu (where, 0.45<=w<1.0<u<=0.08) has a lattice constant very close to that of (AlGa1- B)0.51 In0.49 P being grown while matching the lattice with a GaAs substrate 11, a good crystal interlace can be formed between an AlGaInP emission layer part 18 and an Alw Ga1-w As1-u Pu layer grown thereon. More specifically, perfect lattice matching with (AlBGa1- B)0.51 In0.49 P can be realized at room temperature by controlling the Al composition (w) and the P composition (u) (e.g. Al0.7 Ga0.3 As0.97 P0.03 ).

This value is applied to a switch 13 which obtains the secondary current I2 and a voltage control system for the power inverter. In this manner, the power factor is controlled constantly to control the relative ratio between the secondary current I2 and the exciting current I0 as instructed.
