Abstract

A variety of monoalkyl, dialkyl as well as trialkyl P-compounds, containing ethyl, isopropyl, and tertiarybutyl rest groups have been synthesized and used for the growth of InP bulk epitaxial layers by low pressure metalorganic vapour phase epitaxy. Almost uncompensated, n-type InP-layers (1.0·10¹⁵ cm^-3 59600 cm^-2 V^-1 s^-1 at 77 K) are realized using the not specifically purified precursor ditertiarybutyl phosphine ((C₄H₉)₂-P-H, DitBuPH) in combination with commercial TMIn. Layer quality has been investigated by means of optical and scanning electron microscopy (SEM), temperature-dependent van der Pauw-Hall as well as photoluminescence (PL) measurements. All results are compared with those obtained by using PH₃ as P-source
