Completed Geant4 materials list

[bene73]

Defined the physical properties for PEN, PTFE and CdZnTe. Now, all elements that are available in SolidStateDetectors.jl can also be used to perform Geant4 simulations.

The fraction field in each of the compound materials denotes the relative mass of the element in terms of the total mass of each molecule. The fractions for each material are calculated in the following way:

• PEN (C₁₄H₁₀O₄)
  • C: $\frac{14 \cdot 12.0107}{14 \cdot 12.0107 + 10 \cdot 1.00794 + 4 \cdot 15.9994}\approx 0.6942$
  • H: $\frac{10 \cdot 1.00794}{14 \cdot 12.0107 + 10 \cdot 1.00794 + 4 \cdot 15.9994}\approx 0.0416$
  • O: $\frac{4 \cdot 15.9994}{14 \cdot 12.0107 + 10 \cdot 1.00794 + 4 \cdot 15.9994}\approx 0.2642$
• PTFE (C₂F₄)
  • C: $\frac{2 \cdot 12.0107 }{2 \cdot 12.0107 + 4 \cdot 18.9994}\approx 0.2402$
  • F: $\frac{4 \cdot 18.9994}{2 \cdot 12.0107 + 4 \cdot 18.9994}\approx 0.7598$
• CdZnTe (Cd_0.9Zn_0.1Te)
  • Cd: $\frac{0.9\cdot 112.411}{0.9\cdot 112.411 + 0.1 \cdot65.38 + 127.6}\approx 0.4300$
  • Zn: $\frac{0.1 \cdot65.38}{0.9\cdot 112.411 + 0.1 \cdot65.38 + 127.6}\approx 0.0278$
  • Te: $\frac{127.6}{0.9\cdot 112.411 + 0.1 \cdot65.38 + 127.6}\approx 0.5422$

But is the fraction the atomic fraction or the mass fraction? Because 0.5,0.05,0.45 looks like atomic fractions to me
