Question

This property produces dispersive Raman peaks that Mildred and Gene Dresselhaus attributed to resonance rather than only increases in the density of states near edges. Thin layers with this property are formed as a consequence of Ostwald’s rule of stages during the process of deposition. This property raises the ratio of the D peak to the G peak, which is very low for graphite. (-5[1])Materials with this property have broad vibrational peaks due to their large values of RMS bond angle deviation. The low packing factor of the random (-5[1])close pack means that losing this property through (-5[1])annealing often raises density. Solids with this property consist of rings and chains governed by (10[1])Zachariasen’s rules (10[1])and are (-5[1])isotropic because they lack long-range order. (10[6]-5[1])For 10 points, (10[1])name this (10[1])property of (10[1])materials that do not form (10[1])crystals. (10[3])■END■ (10[7]0[1])

ANSWER: amorphous solids [accept glassy or glasses or vitreous solids; prompt on metastability or metastable; prompt on isotropic until read; prompt on non-crystalline or polycrystalline until “crystals” is read; prompt on disordered or randomly packing until “random” is read]
