In this paper, we report the growth and characterization of II-VI devices grown by molecular beam epitaxy (MBE). The n-type doped ZnSe epilayers were obtained using iodine fom an electrochemical cell and nitrogen from a RF plasma source was used for p-type doping. Capacitance-voltage (C-V) electrochemical profiling of layers and devices has been used to ensure uniform n-type and p-type doping. The nitrogen doped epilayers show a compensation process which leads to the suggestion of a new deep donor which is a complex, such as the (VSe-Zn-NSe) single donor which involves native Se vacancies. The fabrication of pn laser diodes and ZnSe/Zn0.82Cd0.18Se quantum well (QW) laser diodes is reported. The pn junctions show blue laser emission between 448-473 nm under pulsed current conditions at 4.2 K and the QW laser diode shows an excellent mode structure and emits at 474.8 nm at 77 K in pulsed mode operation. © 1993.
