Mechanical twisting of hexagonal boron nitride (hBN) layers modulates embedded quantum emitters at room temperature, achieving 100-meV tuning. Researchers have demonstrated a new method for tuning quantum emitters by mechanically twisting stacks of van der Waals crystals, achieving a measurable shift of over 100 milli, electron volts in their emission properties. Utilizing van der Waals sta... [11664 chars]
