Chemical beam epitaxy (CBE) growth of very high purity InP with Hall m
obility as high as 238 000 cm2/V s at 77K and with a peak value of 311
000 cm2/V s at 50K and residual impurity concentration of 6 x 10(13)
cm-1 at 77K is reported for an InP layer grown at 500-degrees-C. These
values are the highest mobility values ever reported for InP grown by
any molecular beam method.
