1 Introduction According to the fundamental principles of thermodynamics, matter naturally evolves toward a state of minimal energy (U).[1-3] This principle underlines the concept of the equilibrium phase of matter, the state with the lowest energy under specific thermodynamic conditions, such as temperature, pressure, and particle number.

1 Introduction From health diagnosis to drug detection, the use of X-rays has become widespread, driving the expansion of many related industries. While the detection of X-rays has evolved almost completely from the use of analogue films to digital data, the generation of X-rays still depends heavily on traditional thermionic X-ray tubes operated by heated filaments or hot cathodes. As the need for small, portable generators is increasing, new types of X-ray generators are needed.

Gate-Tunable Rectification and Photoresponse in a MoTe2/SnS2 Van der Waals Heterostructure P-N Diode The p-n junction, one of the prominent electrical components capable of being utilized in electronics and optoelectronics, has attracted renewed interest due to recent research in two-dimensional (2D) materials. In this work, we constructed a heterostructure p-n diode based on MoTe2 and SnS2.
