a–d Bias dependent STM topographs of the Se surface. e–h DFT simulations of the Se termination with a constant tip height of 3 Å (see “Methods”). i A representative Fourier Transform of the Se termination. j Linecut taken along \({{{\bf{Q}}}}_{Se}^{1}\) as defined by red dotted line in (i) for different biases, with \({{{\bf{q}}}}_{2ao}^{1}\) and \({{{\bf{Q}}}}_{Se}^{1}\) identified. k, l Same as (j) but taken along \({{{\bf{Q}}}}_{Se}^{2}\) and \({{{\bf{Q}}}}_{Se}^{3}\), respectively. STM setup conditions: a Vsample = −200 mV, Iset = 100 pA; b Vsample = −100 mV, Iset = 100 pA; c Vsample = 100 mV, Iset = 100 pA.d Vsample = 200 mV, Iset = 100 pA.
