A comparison of (100) Hg1-xCdxTe and Hg1-xZnxTe grown by molecular beam epitaxy

  • 1. AT and T Labs., Holmdel, NJ (USA)

Description

Films of HgCdTe with x ≤ 0.6 and of HgZnTe with x ≤ 0.26 have been grown by molecular beam epitaxy (MBE). Very high electron mobilities have been achieved for both materials in the small bandgap region. Hall mobilities at 77K reach 4.8x105cm2/V-s for Hg0.82Cd0.18Te, and 3.1x105 cm2/V-s for Hg0.87Zn0.13Te. HgCdTe growth was easily extended to the 1.5 - 3 μm wavelength range. Attempts to extend HgZnTe to these bandgaps were unsuccessful due to defects that are induced by surface roughness in high Zn-content films. These results suggest that HgCdTe is the more suitable material for MBE growth for near infrared applications
