The existence of dark matter has been inferred through many
astrophysical phenomena, but the nature and origin of dark matter are
still unknown. For over a decade, the SuperCDMS (Cryogenic Dark Matter
Search) collaboration has been one of the leading direct dark matter
search experiments using low-temperature semiconductor detectors to
identify the dark matter-nucleus interaction. The nuclear recoil
energy induced by dark matter-nucleus scattering is measured through
phonon (lattice vibration) and ionization signals. SuperCDMS has the
best dark matter-nucleon cross section limits in the world for
low-mass dark matter particles with masses between 2-5GeV/c2. With
unique discovery potential for low-mass dark matter and complementary
search at higher-mass dark matter, SuperCDMS plays a vital role in
dark matter search. We are now moving forward with the SuperCDMS
SNOLAB experiment, a DOE/NSF funded direct detection dark matter
search program. In this talk, I will present the recent result of the
CDMS low-ionization threshold experiment (CDMSlite) and then discuss
the scientific goals and the recent status of the SuperCDMS SNOLAB
project.
