The authors would like to correct the following:

Replacement of Fig. 1B with new image and caption:
The authors would like to replace Fig. 1B with spectra results from confocal Raman microscopy. TEM results (Fig. 1B) were included in the original paper without consensus and knowledge of the scientist who did the TEM analysis before the submission. From the TEM analysis, it was concluded that the films did not show the presence of any carbon layers, but the presence of cracks. Figure 1B was obtained from one of the cracks as pointed out by the scientist who did the TEM analysis, and thus cannot be used to represent the carbon layer. Given that we do not have the TEM results that show the claimed carbon layers, the original Fig. 1B will be replaced with a new Fig. 1B, a result from a confocal Raman microscope that indicated the existence of carbon layers beneath the silica layer. The carbon black layer is identified by two distinct D and G bands near 1320 cm−1 and 1610 cm−1, respectively.

New Fig. 1B: Raman spectra obtained by confocal Raman Microscope showing the existence of carbon black layer as laser is penetrated and focused beyond the top silica layer. Peak at ~ 520 cm−1 is from the crystalline silicon substrate, whereas the peak at ~ 950 cm−1 representing Si–O–Si vibration from the coated silica layer. The carbon black layer is characterized by two distinct D and G bands near 1320 cm−1 and 1610 cm−1, respectively.

The sentence in the Results and discussion of the article: Pyrolysis of sugar at temperature > 200 °C forms polycyclic aromatic carbon black sheets [8] (the carbon black layer is only 10–20 nm thick (Fig. 1B))
Should read “Pyrolysis of sugar at temperature > 200 °C forms polycyclic aromatic carbon black sheets [8]”.
-
3.
The sentence in the Materials and methods of the article: About 0.111 g of sugar was mixed with 6.408 g EtOH + 20 mL deionized H2O to form the coating solution for the sugar layer. The sugar solution was filtered using a 0.25 mm pore filter before coating
Should read “About 0.111 g of sugar was mixed with 6.408 g EtOH +20 μL deionized H2O to form the coating solution for the sugar layer. The sugar solution was filtered using a 0.25 μm pore filter before coating”.

4.
The sentence in the Materials and methods of the article: Approximately 20–30 mL sol–gel silica solution or sugar solution was used for each layer
Should read “Approximately 20–30 μL sol–gel silica solution or sugar solution was used for each layer”.
