Sh. Song et al., CYCLOTRON MASS OF 2-DIMENSIONAL HOLES IN STRAINED SI SI0.88GE0.12/SI HETEROSTRUCTURES/, Solid state communications, 96(2), 1995, pp. 61-63
We have observed cyclotron resonance of the two-dimensional holes in s
trained layer Si/Si0.88Ge0.12/Si heterostructures with densities p(s)
= 3.7 x 10(11) cm(-2) and 4.2 x 10(11) cm(-2) in magnetic fields from
4T to 8T at 4.2K. Our data yield a mass value of (0.18 +/-0.02)m(e), i
n good agreement with the calculated in-plane mass of the Mj = +3/2 ''
heavy hole'' band.
