Direct observation of electronic band gap and hot carrier dynamics in GeAs semiconductor
Zailan Zhang, Jiuxiang Zhang, Gangqiang Zhou +9
Germanium arsenide (GeAs) is a layered semiconductor with remarkably anisotropic physical, thermoelectric and optical properties, and a promising candidate for multifunctional devi…
Dynamics of electronic states in the insulating Intermediate surface phase of 1T-TaS
Jingwei Dong, Weiyan Qi, Dongbin Shin +14
This article reports a comparative study of bulk and surface properties in the transition metal dichalcogenide 1T-TaS. When heating the sample, the surface displays an intermed…
Electronic dispersion, correlations and stacking in the photoexcited state of 1T-TaS
Jingwei Dong, Dongbin Shin, Ernest Pastor +11
Here we perform angle and time-resolved photoelectron spectroscopy on the commensurate Charge Density Wave (CDW) phase of 1T-TaS. Data with different probe pulse polarization a…
Dichroism in time-resolved ARPES and valence band orbital nature in BaNiS2
J. Zhang, Z. Chen, J. Caillaux +7
Time-resolved ARPES gives access to the band structure and ultrafast dynamics of excited electronic states in solids. The orbital character of the bands close to the Fermi level is…
Orbital contributions in the element-resolved valence electronic structure of Bi2Se3
Cheng-Tai Kuo, Shih-Chieh Lin, Jean-Pascal Rueff +9
In this work, we studied the bulk band structure of a topological insulator (TI) Bi2Se3 and determined the contributions of the Bi and Se orbital states to the valence bands using…
Ultrafast electrons dynamics reveal the high potential of InSe for hot carrier optoelectronics
Zhesheng Chen, Christine Giorgetti, Jelena Sjakste +9
We monitor the dynamics of hot carriers in InSe by means of two photons photoelectron spectroscopy (2PPE). The electrons excited by photons of 3.12 eV experience a manifold relaxat…
Time resolved photoemission spectroscopy of electronic cooling and localization in CHNHPbI crystals
Zhesheng Chen, Min-i Lee, Zailan Zhang +10
We measure the surface of CHNHPbI single crystals by making use of two photon photoemission spectroscopy. Our method monitors the electronic distribution of photoexcite…
