Neutralization of low energy Na scattered from InAs(001)
Haoshan Zhu, Chao Lian, Bryan M. Wong +1
The neutralization probability of low energy Na ions scattered from In- and As-rich InAs(001) surfaces is measured by time-of-flight spectroscopy. It is found that the neutra…
Indirect but Efficient: Laser-Excited Electrons Can Drive Ultrafast Polarization Switching in Ferroelectric Materials
Chao Lian, Zulfikhar A. Ali, Hyuna Kwon +1
To enhance the efficiency of next-generation ferroelectric (FE) electronic devices, new techniques for controlling ferroelectric polarization switching are required. While most pri…
Ultrafast carrier relaxation and its Pauli drag in photo-enhanced melting of solids
Chao Lian, S. B. Zhang, Sheng Meng
Ultrafast light-matter interaction is a powerful tool for the study of solids. Upon laser excitation, carrier multiplication and lattice acceleration beyond thermal velocity can oc…
Cooperative evolution of intraband and interband excitations for high harmonic generation in strained MoS2
Meng-Xue Guan, Chao Lian, Shi-Qi Hu +4
Modulating electronic structure of two-dimensional (2D) materials represents an exciting avenue for tailoring their optoelectronic properties. Here, we identify a strain-induced, c…
Charge Density Wave Hampers Exciton Condensation in 1T-TiSe
Chao Lian, Zulfikhar A. Ali, Bryan M. Wong
The Bose-Einstein condensation of excitons continues to garner immense attention as a prototypical example for observing emergent properties from many-body quantum effects. In part…
Ultrafast charge ordering by self-amplified exciton-phonon dynamics in TiSe
Chao Lian, Sheng-Jie Zhang, Shi-Qi Hu +2
The origin of charge density waves (CDW) in TiSe has long been debated, mainly due to the difficulties in identifying the timescales of how and when the excitonic pairing and e…
