Our thin film vacuum evaporator successfully helped Dr.Liu publish 3 heavyweight research papers in IEEE Electron Device LETERS

hot wire! Dr. Liu from the Institute of Optoelectronics successfully published three heavyweight papers in IEEE ELECTRON DEVICE LETTERS using our thin film vacuum evaporator and Probe Station. Here are the details of the paper:

**The function and principle of the Thin Film Vacuum Evaporator are as follows:

###Function

1. * * Thin film deposition :

-This device is used to deposit uniform thin films on the surface of substrates and is widely used in fields such as electronic devices, optical devices, solar cells, etc.

2. * * Material selection :

-It can evaporate various materials, including metals, oxides, and polymers, to meet different application needs.

3. * * High quality film :

-Deposition of thin films in a vacuum environment can reduce the influence of impurities and gases, thereby obtaining high-purity and high-quality thin films.

4. * * Precise Control :

-By controlling the evaporation rate and deposition time, the thickness of the film can be precisely adjusted to ensure compliance with technical requirements.

###Principle

1. * * Vacuum environment :

-Thin film evaporators operate under high vacuum conditions, typically with a vacuum degree of 10 ^ -6 to 10 ^ -8 Torr. This environment reduces the interference of gas molecules on the evaporation material.

2. * * Material Heating :

-Place the material to be deposited in an evaporation source and heat it to its evaporation temperature through resistance heating, electron beam heating, and other methods to transform it into a gaseous state.

3. * * Evaporation and sedimentation :

-The evaporated material diffuses in vacuum and ultimately deposits on the cooled substrate, forming a thin film. During the deposition process, gas molecules condense on the surface of the substrate, forming a solid thin film.

4. * * Thin film growth :

-The growth process of thin films can be adjusted by controlling the evaporation rate, substrate temperature, and deposition time to achieve films of different thicknesses and properties.

###Summary

Thin film vacuum evaporator heats materials in a vacuum environment to evaporate and deposit them on the substrate, forming a uniform thin film. This process has strict requirements for material selection, deposition rate, and environmental conditions to ensure the quality and performance of the film.
