Query: An effect of Sm vacancies on the hybridization gap in topological Kondo
  insulator candidate SmB$_6$   A necessary element for the predicted topological state in Kondo insulator
SmB$_6$ is the hybridization gap which opens in this compound at low
temperatures. In this work, we present a comparative study of the in-gap
density of states due to Sm vacancies by Raman scattering spectroscopy and heat
capacity for samples where the number of Sm vacancies is equal to or below 1 %.
We demonstrate that hybridization gap is very sensitive to the presence of Sm
vacancies. At the amount of vacancies above 1 % the gap fills in with impurity
states and low temperature heat capacity is enhanced.
