Submonolayer cyclic epitaxy was used for the first time to obtain a bulk la
yer of BeCdSe solid solution 100 nm thick with a Be content close to 46%, w
hich corresponded to the composition lattice-matched to the GaAs substrate.
In addition, low-temperature lasing at a wavelength of 460 nm with a thres
hold power density of about 40 kW/cm(2) in a structure with multiple ZnSe/B
eCdSe quantum wells was also attained for the first time. The band-bending
parameter in the BeCdSe solid solutions was estimated at 4.5 eV. (C) 2001 M
