Thermodynamic Properties of Solid Binary Antimonides

“…The most reliable experimental results are heat-capacity measurements. Two low-temperature studies produced virtually identical values of S ° 298 (64.2 and 63.9 J/(mol K)). , The results of three high-temperature C p measurements are also very similar. ,, Table includes S ° T for AlSb, calculated using the results of Yamaguchi et al and Malkova et al , Using the entropy for the elements calculates entropies of formation for AlSb of −9.87 J/(mol K) at 298.15 K and −13.92 J/(mol K) at 800 K.…”

“…The most common experimental method for high-temperature heat-capacity measurements has been drop calorimetry. ,− Copper-block calorimeters have been the most popular, but diphenyl ether has also been used, as has water on at least one occasion. More recent investigations have relied on continuous methods, including ac calorimetry, , high-temperature adiabatic calorimetry, ,,,− and differential scanning calorimetry. , …”

“…The only low-temperature measurement of C p for GaSb is that of Piesbergen, which established S ° 298 = 76.06 J/(mol K). Above-ambient measurements include those of Kochetkova and Rezukhina (293–1000 K), Cox and Pool (298–985 K), Yamaguchi et al (800–991 K), , Lichter and Sommelet (298–985 K), and Malkova et al (298–798 K) . The results of the last two investigations are nearly identical and are used in Table to calculate S ° T for the compound.…”

Lamellar Twinning in Semiconductor Nanowires

“…r Calculated based on the equation for the step energy of a Kossel crystal, h γ = q 1/3 × [( W /3) − k b T m ln(1 + 2 exp(− W / k b T m ))], where h is the (111) step height, q is the atomic density, W is 0.45 times Δ H (the latent heat of fusion per atom), k b is the Boltzman constant, and T m is the melting temperature. Δ H values of 12.4 × 10 -13 erg, and for InAs of 6.1 × 10 -13 erg, were used for GaP and InAs, respectively. s The liquid surface tension of eutectic melts of Au and Si has been observed to decrease monotonically from a maximum of 1140 erg cm -2 for pure Au to 865 erg cm -2 for pure Si .…”
