The Model Evap40-Li is a thermal vacuum evaporator tailored to tackle the inherent challenges of lithium evaporation, especially its reactivity and the need for a precise temperature control. Lithium's tendency to bond with oxygen, nitrogen, or moisture in the air is a major obstacle. The Evap40-Li addresses this by allowing lithium to remain in an argon atmosphere during transfer from re-fling crucible with Li metallic pallets (Glove Box) to the vacuum system. This enclosed handling minimizes exposure to reactive gases, preserving the lithium purity until it's ready for evaporation.
The SH500 Heater, equipped with a PID controller, offers versatile operation through both manual and PC-based control interfaces. This allows users to regulate either the current or the temperature with precision, a critical capability for managing lithium evaporation processes. By enabling fine-tuned adjustments, the SH500 ensures reliable and uniform vapor deposition.

Effusion cell model Evap40 is a miniature vapor source of wide range solid state materials that are suitable for evaporation from crucible by thermal radiation from the surrounding tungsten heater.
The temperature range is from 50 °C to 1200 °C. It is designed for deposition of uniform thin films under ultra high vacuum conditions onto the substrate from sub-monolayer thickness to multilayered thin film.

The electron beam evaporator, model EB-Evap 40 is a compact vapour source of almost any solid state material that is needed for deposition of thin film on substrate.
The temperature range for material evaporation is from 100 °C to 2300 °C. Evaporation is directly from 2 mm diameter rod or indirectly from the small crucible.
The unit is very compact and suitable for any UHV system.

The electrospray ionization deposition method (ESID) is based on the atomic dispersion of fluid that contains molecules or nano-articles under high electric field onto a substrate. The spray nozzle is connected to a high-voltage power supply while the target substrate is grounded. This creates a potential difference and therefore, a strong electric field which builds up at the end of the nozzle which forms a Taylor cone. The Taylor cone then deforms into a jet at the tip and disperses into a fine mist. Within the mist there are charged clusters that deposit onto the substrate due to ionic attraction which form a nanofilm. (For illustration of the above, see Figure 2.)
During the fluid dispersion, there are several processes occurring such as Taylor cone formation, charge transfer, solution evaporation, Coulomb fission, impact on the surface, nucleation, diffusion and nanofilm growth.
