In operando cryo-STEM of pulse-induced charge density wave switching in TaS$_2$

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: James L Hart, Saif Siddique, Noah Schnitzer, Stephen D. Funni, Lena F. Kourkoutis | Summary: The charge density wave (CDW) material 1T-TaS$_2$ exhibits a pulse-induced insulator-to-metal transition, which shows promise for next-generation electronics such as memristive memory and neuromorphic hardware. However, the rational design of TaS$_2$ […]

Phonon-Dressed Third-Harmonic Generation in Diamond

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses, , | Summary: We demonstrate a strong, elastic, frequency-upshifting optical polarizability that accompanies sum-frequency driving of Raman phonons and two-photon absorption, extending the duality of structural and optical property modification recently observed in light-driven phononics. The effect, phonon-dressed third-harmonic generation (THG), […]

Phonon-Mediated Third-Harmonic Generation in Diamond

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses, , | Summary: We observe strongly anisotropic third-harmonic generation mediated by resonant sum-frequency driving of Raman phonons with THz light, extending light-induced dual control of structural and optical properties in solids. Either strong enhancement or strong suppression of the third harmonic […]
