How do I get such a notation for vectors in LaTeX?

@nlatexg: Try this in your TeX file: \newcommand{\vect}[1]{\accentset{\rightharpoonup}{#1}} with the package accent — Saravanan, Dec 19 '16 at 15:53

See, if this is what you looking for:

\documentclass[preview, margin=3mm]{standalone}
\usepackage{harpoon}% <---

\begin{document}
$\overrightharp{a}$    $\overrightharp{AB}$  
\end{document}
