abstract = {Intriguing anisotropic electrical and optoelectrical properties 

 in two-dimensional (2D) materials are currently gaining 

 increasing interest both for fundamental research and emerging 

 optoelectronic devices. Identifying promising new 2D materials 

 with low-symmetry structures will be rewarding in the 

 development of polarization-integrated nanodevices. In this 

 work, the anisotropic electron transport and optoelectrical 

 properties of multilayer 2D ternary Ta2NiSe5 were systematically 

 researched. The polarization-sensitive Ta2NiSe5 photodetector 

 shows a linearly anisotropy ratio of $approx$3.24 with 1064 nm 

 illumination. The multilayer Ta2NiSe5-based field-effective 

 transistors exhibit an excellent field-effective mobility of 

 161.25 cm2·V-1·s-1 along the a axis (armchair direction) as well 

 as a great current saturation characteristic at room 

 temperature. These results will promote a better understanding 

 of the optoelectrical properties and applications in new 

 categories of the in-plane anisotropic 2D materials.},
