Is there a way to adjust the height of \vline?

You can use the ! feature of the array package, together with \vline; however, it would be better not using vertical rules at all, as shown in the second table.
\documentclass{article}
\usepackage{array} % necessary for the shorter rule
\usepackage{booktabs} % for the second example
\begin{document}
\begin{tabular}{|c|c|}
\hline
\multicolumn{2}{|c|}{Header 1}\\
\multicolumn{1}{|c!{\vline height .8\ht\strutbox}}{Subheader 1} & Subheader 2 \\
\hline
Cell 1 & Cell 2 \\
\hline
\end{tabular}
\bigskip
\begin{tabular}{cc}
\toprule
\multicolumn{2}{c}{Header 1} \\
\addlinespace
Subheader 1 & Subheader 2 \\
\midrule
Cell 1 & Cell 2 \\
\bottomrule
\end{tabular}
\end{document}
A | in the table format specification means a vertical rule:
\documentclass{article}
\begin{document}
\begin{table}[ht]
\caption{Model Input Information: Materials}
\centering
\begin{tabular}{c | c | c}
\hline\hline
Available Materials & Material Input Parameters & Description \\
\hline
Fused Silica (delta eV = 9) & alpha & Avalanche Coefficient [$cm{^2}$/J] \\
Fused Silica (delta eV = 7.5) & delta eV & Material Band Gap [eV] \\
GaAs & me & Effective Electron Mass [kg] \\
ZnSe & n0 & Linear Refractive Index \\
Ge & n2 & Non-Linear Refractive Index \\
$HfO_2$ & T & Effective Decay Constant [fs] \\
$TiO_2$ & & \\
$Ta_2O_5$ & & \\
$Al_2O_3$ & & \\
$SiO_2$ & & \\
\hline
\end{tabular}
\label{table:MaterialInputs}
\end{table}
\end{document}
Some remarks:
I'd suggest you not to use vertical rules, and use the features from the
booktabspackage.To properly typeset chemical compounds, you can use a variety of packages. In the example below I used
\cefrommhchem.To appropriately typeset units, I'd suggest the
siunitxpackge.Notice also that the placement specifier should go inside square brackets, as in
\begin{table}[ht]
An example code showing some of these suggestions:
\documentclass{article}
\usepackage{booktabs}
\usepackage{siunitx}
\usepackage{mhchem}
\sisetup{per-mode = symbol}
\begin{document}
\begin{table}[ht]
\caption{Model Input Information: Materials}
\centering
\begin{tabular}{c c c}
\toprule
Available Materials & Material Input Parameters & Description \\
\midrule
Fused Silica (delta eV = 9) & alpha & Avalanche Coefficient [\si{\cm\squared\per\joule}] \\
Fused Silica (delta eV = 7.5) & delta eV & Material Band Gap [\si{\electronvolt}] \\
\ce{GaAs} & me & Effective Electron Mass [\si{\kilogram}] \\
\ce{ZnSe} & n0 & Linear Refractive Index \\
\ce{Ge} & n2 & Non-Linear Refractive Index \\
\ce{HfO_2} & T & Effective Decay Constant [fs] \\
\ce{TiO_2} & & \\
\ce{Ta_2O_5} & & \\
\ce{Al_2O_3} & & \\
\ce{SiO_2} & & \\
\bottomrule
\end{tabular}

Best Answer
If the height and depth of a
\vruleis not specified, then they are taken from the surrounding box. But it is possible to specify them explicitly:
