<p>Dear QE users,</p>
<p><br>
</p>
<p>Now I want to use QE to get the STM simulation in a kind of 2D materials surface.</p>
<p><br>
</p>
<p>How to choose the sample bias in STM simulation?</p>
<p><br>
</p>
<p>following is my pp.x input file</p>

<div>&INPUTPP</div>
<div> prefix='4-4',</div>
<div> sample_bias = -0.0735d0 ,</div>
<div> plot_num= 5 ,</div>
<div>/</div>
<div>&PLOT</div>
<div> nfile = 1 ,</div>
