– Excitons in atomically thin semiconductors are confined by an in-plane potential well created by a remote moire potential
– Electrostatic moire potential provides a new platform to modulate light properties in spatial and spectral domains
– Confined excitons exhibit hysteresis behavior influenced by t-hBN
