摘要: Abstract Two-dimensional doping sheets (“δ-doping”) are integral parts of many novel semiconductor device concepts. Their practical realization in silicon (Si), however, was long delayed by the difficulty to introduce dopants into Si a well-controlled way during epitaxial growth. Recent advances understanding growth and incorporation have overcome these difficulties opened new field materials research. In this article, we review growth, processing, characterization epitaxially grown 5-doped Si. Furthermore, discuss electronic subband states such structures. Finally, give an overview concepts that use 5-doping analyze their properties.
