SPECIFIC HEAT
Glattli, Andrei, Williams PRL 87
n=1.02x108 cm-2
TD=0.93Tm
Calculated phonon
heat capacity using
wl+=wp2-5wt2
wt=ctk
Same with renormalized ct
ct 2(T)=ct 2(0)(1-0.3T/Tm)
Low temperature limit
C~T2 not attained
Cz2kB for TzTm
classical limit (low TD)
No defect contribution for Tɘ.8Tm.
Consistent with theory
