Photoluminescence and Excitation Studies of Semiconductors

A photolummescence (PL) study of Be and Au ion-implanted GaN is pre­ sented GaN samples were implanted and selectively annealed prior to excita­ tion by a HeCd laser The resulting luminescence was dispersed by a grating spectrom eter and detected using a photomultiplier tube Be is proposed to form a shallow acceptor in GaN and is thus critical to device development and performance From analysis...

Nonlinear Optics Basics: Kramers-Krönig Relations in Nonlinear Optics

Twinning and Nonlinear Optics

A comprehensive theory of quasi-phase-matched (QPM) three-wave interactions in twinned plates of q3m semiconductors is developed. The 180* phase change required by QPM is studied by treating the nonlinear polarization as a bilinear form in the applied electric field and decomposing it into invariant and sign changing parts under a 2-fold rotation of an arbitrary crystal lattice. A new 3 X 3 mat...
