The xlsx files include all data that was presented in the manuscript. The files are named as the corresponding figures.
Electrical measurements: I-V characteristics were measured in a wide temperature range in a superconducting magnet system (Oxford Instruments). Yokogawa 7651 was used as a voltage source, and Aglient 34410A multimeter with Ithaco 1211 preamplifier were used to measure drain- source voltage. Keithley SMU 2400 source meter was used to set backgate voltages.
Optical spectroscopy: measurements were performed in an optical helium flow cryostat (Oxford Instruments). The excitation source for microphotoluminescence was a 532 nm continuous wave laser. The white light source for microreflectance was a Tungsten-Halogen Light Source (Thorlabs). The light was spatially filtered through a 50 μm pinhole, which yields the final spot size of ∼ 4 μm. The laser light and the white light were focused on the sample surface by 0.75 NA and 50× microscope objective (Mitutoyo). The same objective was used to collect the output signal, which was then directed to the spectrometer (500 mm focal length, 300 groove/mm grating and 150 μm slit width) equipped with a liquid nitrogen cooled CCD camera (Princeton Instruments).
