Indium thallium phosphide: experiments versus predictions

We have attempted synthesis of TIP from melt and InTIP from solution by liq uid-phase epitaxy (LPE). X-ray diffraction measurements of the melt-grown m aterial reveal the presence of orthorhombic compound which is identified as TIP5 by comparison with the published data in literature. Energy dispersiv e X-ray analysis suggests the composition of the crystallites to be TIP3. B y LPE growth, smooth layers from In and In + TI solutions are grown on InP substrates. However, there is no significant incorporation of thallium in t he epitaxial layers. (C) 2000 Elsevier Science B.V. All rights reserved.
