Our group mainly study molecular self-assembly, surface reactions, model catalysis and ion chemistry at surface. We have successively purchased several sets of E-beam Evaporators and Controllers from ACME (Beijing) Technology Co., Ltd., for evaporating transition metals such as Fe and Au. The E-beam Evaporators and Controllers provided by ACME are easy to use and stable in performance, which helps us obtain high-quality experimental data. In addition, the ACME technical team provides free installation and operation instructions, solves the problems we encounter in a timely manner, which brings great convenience to our scientific research work. In conclusion, we are satisfied with the products and services of Acme.

Last year, we purchased a set of non-standard customized cryogenic STM (scanning tunneling microscope) system, to replace the STM part of our existing STM-MBE system. This LT-STM system can reach an operating temperature of less than 10K, it has a large scanning range of 1.5 × 1.5 × 0.5 μm at low temperatures, and can obtain clear atomic images. This customized system is well compatible with our existing MBE system, and also has in-situ evaporation ports for in-situ deposition or doping of samples.

In 2017, we purchased tip etching instrument, K-cell evaporator and controller from ACME, and have been using it till now. The K-cell evaporator is installed on the STM-MBE system, which is mainly used to evaporate organic molecular materials. In the past few years, the evaporator has been working stably without any quality problems, and the samples we got with it are uniform. The tip etching instrument is mainly used to prepare tungsten tips. It’s ben working well and we etched many high-quality tips with it.

We recommend the STM system, K-cell evaporator and tip etching instrument produced by ACME (Beijing) Technology Co., Ltd. to domestic and foreign scientists and researchers.

Our group mainly studies low-dimensional superconducting and topological materials. Recently, we purchased 5 sets of K-cell evaporators and matching temperature controllers from ACME (Beijing) Technology Co., Ltd., and we’ve installed them on a STM-MBE system. In the process of purchasing, assembling and testing these evaporators, the ACME team provided us with professional advice and technical support, which helped us a lot. When there is a problem, ACME engineers can come to our lab to solve it in time.

Now these effusion cells are mainly used for evaporating materials like Fe, Te, Pb, Se, etc. They work well, the beam flux is stable, high-quality thin film samples can be obtained.

I have purchased E-beam and K-Cell evaporators produced by ACME team, as well as the matching controllers. The evaporators are installed on our UHV STM-MBE-LEED system. The E-beam evaporator is mainly used for evaporating Si, Ge, C etc., and the K-Cell evaporator (Effusion Cell) for Se, Te etc. The evaporators and controllers produced by ACME are easy to operate and have highly stable performance. Especially the K-Cell evaporator can be installed face down, which is very suitable for evaporating certain characteristic materials, that is, 1/3 of the boiling point of the material is less than its melting point. Here I am willing to recommend the evaporators and controllers produced by ACME (Beijing) Technology Co., Ltd. to scientists and researchers at home and abroad.

My lab has ordered two sets of e-beam evaporator and the matching controller from ACME (Beijing) Technology Co., Ltd., installed in the photoelectron spectroscopy experimental line station and the catalysis and surface science experimental station, mainly to evaporate metals such as Zr, Ce, Au, Cu, Ag etc. The crucible of the e-beam evaporator is easy to replace; the flux of the controller is very stable, the operation is convenient and simple with touch screen. It's easy to get high-quality thin film samples, which ensures the smooth progress of further analysis and testing. During the period when the systems were open to external users, their excellent stability was well received.

The ACME team can provide timely and professional feedback and technical support to our needs and questions.

As a longtime customer, I've always been happy with the high-performance products and efficient services from ACME (Beijing)

Technology Co., Ltd. We currently have ACME e-beam evaporators, k-cell evaporators and the matching controllers installed in my

variable temperature scanning proble microscopy system. The e-beam evaporators are mainly for the evaporation of metal, such

as Pt, Pd. The K-cell evaporators are used for organic molecule depositions. With the excellent stability and controllability, the ACME

products have been extremely important tools for the fabrications of 2D materials, single-atom-alloy catalysts, and molecular

nanostructure  in my laboratory. In addition, we are using ACME tip etching unit to fabricate plasmonic probes for ultrahigh vacuum

tip-enhanced Raman spectroscopy. Below are some experimental data collected using their high-quality products.
ACME (Beijing) has proven to be a very reliable and efficient supplier. I have been delighted with experience with them, therefore I'm

writing this letter to endorse them for their great work.

Our research interest is in atomically-precise design of new catalytic materials using a combined wet-chemistry and atomic layer deposition (ALD) method. Because the standard commercial ALD system is difficult to meet my experimental needs, ACME (Beijing) Technology Co., Ltd. customized an atomic layer deposition system according to our needs, and the system was officially put into operation in March 2019. So far, the system has been running well, the performance is very stable, and the repeatability of the experiment has exceeded my expectations. My research group has obtained a series of high-quality research data by using this system, and is gradually collating articles and submitting for publication. The design of the system is novel and reliable, while meeting our needs, it ensures the easy operation and scalability of the system. The technical service team responded to our problems and suggestions in a timely manner, and can provide effective solutions in a short period of time, which provides a very important guarantee for the smooth progress of our experiments.

Our research is based on synchrotron radiation photoelectron spectroscopy/absorption spectroscopy and scanning tunneling microscopy techniques to carry out the fine characterization and physical property correlation of the surface and interface electronic structure and atomic structure of low-dimensional material. We have extremely high requirements for the stability, repeatability and easy operation of the experimental equipment. We purchased e-beam evaporator and e-beam controller from ACME (Beijing) Technology Co., Ltd., which are mainly used to evaporate metals such as Pt, Co, and Fe etc. The evaporator has been used for nearly 2 years, during which there's no quality problem, the performance is very stable, the material reloading is convenient, and the controller touch screen is simple to operate. From sales to technical support, they can offer highly efficient service.
