Abstract
We describe an independently valved solid arsenic and phosphorus effus ion source for molecular beam epitaxy. A common posteffusion hot zone and orifice ensure constant flux ratios of arsenic, phosphorus, and mi xed species in the beam. With this source, we have demonstrated molecu lar beam epitaxial growth of GaAs1-xPx layers with better than +/-0.4% compositional variation over a 3-in. -diam substrate.
