Growth and characterisation of Mg-based low dimensional systems for blue-green optoelectronics

A brief overview of the state-of-the-art of the growth and characterization of Mg-based II-VI heterostructures is reported. Recent studies on MgSe binary compound, ZnMgSe ternary alloy and ZnSe/ZnMgSe multiple quantum wells (MQWs) grown by metalorganic vapour phase epitaxy (MOVPE) are presented. MgSe layers are shown to be mosaics made of two main RS crystal orientation.
