## Description

- description: We introduce a peak fitting method to estimate the model parameters
    and the number of peaks without using the conventional trial-and-error approach.
    The proposed method automatically removes excess peaks using maximum a posteriori
    estimation. The computation is performed efficiently by the spectrum-adapted expectation–conditional
    maximisation algorithm with deterministic annealing. We apply the proposed method
    to synthetic and experimental data from a tunnel field-effect transistor. The
    proposed method identified two peak components in the experimental data from a
    MoS2 sheet, which are interpreted to be the Mo 3d3/2 and Mo 3d5/2 peaks. No peaks
    were detected on the p-WSe2 sheet and hexagonal boron nitride (h-BN) within the
    measured binding energy range.
