A Modified Approach to Determine the Hall Parameters of Epitaxial GaSb Grown on Conductive GaSb Substrate

S. K. Noh, J. O. Kim, S. J. Lee


A modified approach, junction Hall effect measurement (JHEM), is tried.  This is a Hall effect measurement effective in determining the Hall parameters of epitaxial layers grown on conductive substrate with no use of insultion layer or semi-insulating (SI) substrate, by applying the built-in potential barrier to electrical isolation.  Prior to examination of GaSb, the utility of JHEM has been proven by demonstrating the Hall parameters taken from a series of epitaxial GaAs n-p junctions, comparing with an equivalent n-GaAs epilayer grown on SI-GaAs substrate.  Using the JHEM approach, finally, we directly determine the Hall parameters of epitaxial p-GaSb layer grown on conductive n-GaSb substrate. 

Keywords: Junction Hall effect measurement (JHEM), Hall parameters, Conductive substrate, P-n junction, Gallium arsenide (GaAs), Gallium antimonide (GaSb)
