  We investigate the thermodynamics of a crystalline solid applying q-deformed
algebra of Fibonacci oscillators through the generalized Fibonacci sequence of
two real and independent deformation parameters q1 and q2. We based part of our
study on both Einstein and Debye models, exploring primarily (q1,q2)-deformed
thermal and electric conductivities as a function of Debye specific heat. The
results revealed that q-deformation acts as a factor of disorder or impurity,
modifying the characteristics of a crystalline structure. Specially, one may
find the possibility of adjusting the Fibonacci oscillators to describe the
change of thermal and electrical conductivities of a given element as one
inserts impurities. Each parameter can be associated to different types of
deformations such as disorders and impurities.
