 Acceptors are in the 3rd group (III), usually B,Al,Ga,In.
 For doners we have:
 \begin{align}

+    %<*eqDopingDonersConcentration>
     n_0 & = N_d               \\

 \subsection{Charge neutrality}
 Every semiconductor is neutral,
 which imposes the following condition:
 \begin{equation}
+    \label{eqChargeNeutrality}
+    %<*eqChargeNeutrality>
     P_0-n_0 + N_d - N_a = 0

 \end{equation}
 where $p_0n_0=n_i^2$.
