The energy band gap and lattice constant of the quaternary alloy Ga[sub x]In[sub 1-x]As[sub y]Sb[sub 1-y] were determined over the entire composition space (x, y) using a correlated function expansion (CFE) technique to interpolate from observed ternary compound data. Considerable ...

d2 represents thelatticeconstant of the compoundsemiconductorconstituting the buffer layer, and d3 represents the averagelatticeconstant of the compoundsemiconductorconstituting the quantum well layer, the value of (d2‒d1)/d1 is ‒3×10‒3 to 3×10‒3, and the value of (d3‒d1)/...
The mean-square amplitudes (measured at 295 K) show a general increase with increasing lattice constant and seem furthermore to reflect the partial ionicity of the compounds. The different phonon models for the lattice dynamics are compared with each other and tested critically against the ...
