✦ Synopsis

Lateral wire arrays have been fabricated from a single modulation-doped GaAs quantum well employing reactive ion etching. Depending on the etch depth, the two-dimensional electron gas (2DEG) in the well acquires different degrees of modulation up to complete confinement. The different regimes are identified by their unique photoluminescence and Raman spectra. Deep-etched wires show plasmon resonances down to a width of (100 \mathrm{~nm}).

We present the Raman and photoluminescence (PL) spectra of CuGaS 2 : Cd grown by iodine transport method. The PL spectra of CuGaS 2 showed both band gap and deep center emission, while for CuGaS 2 : Cd the deep center emission was suppressed completely and a new strong emission at 2.31 eV with an ac
