In this paper, we study the following nonlinear Dirac equation
$\begin{equation*}-i\varepsilonα·\nabla w+aβ w+V(x)w = g(|w|)w, \ x∈ \mathbb{R}^3, \ {\rm for}\ w∈ H^1(\mathbb R^3, \mathbb C^4), \end{equation*}$
where
$a > 0$
 is a constant,
$α = (α_1, α_2, α_3)$
,
$α_1, α_2, α_3$
 and
$β$
 are
$4×4$
 Pauli-Dirac matrices. Under the assumptions that
$V$
 and
$g$
 are continuous but are not necessarily of class
$C^1$
, when
$g$
 is super-linear growth at infinity we obtain the existence of semiclassical solutions, which converge to the least energy solutions of its limit problem as
$\varepsilon \to 0$
.
Keywords: Dirac equation, semiclassical solutions, concentration.
