GWANGJU, South Korea, Sept. 13, 2023 /PRNewswire/ -- Remote epitaxy has been gaining attention in the field of semiconductor manufacturing for growing thin films that copy the crystal structure of the template, which can later be exfoliated to form freestanding membranes. However, harsh epitaxy conditions can often cause damage to the template materials, such as in the case of remote epitaxy of GaN thin films, promising materials for light-emitting diodes, photodetectors, and power electronic devices, on graphene/AlN templates.

Key Points:

GaN remote heteroepitaxy has not been achieved by a standard metal–organic chemical vapor deposition (MOCVD) technique due to the high temperatures involved in the process.
The researchers first performed an annealing test at 950 °C for 5 minutes to check the thermal stability of graphene on AlN.
The exfoliation of the thus-grown GaN thin films was used as a proof of success of the remote epitaxy process.
These results exemplify the importance of chemical and topographic properties of templates for successful remote epitaxy," highlights Prof. Lee.

Key Points:

Figure 2 shows the disinfection performance of the mercury lamp system (left) and the experimental Klaran WR (right).
UVC LEDs have been developed as a mercury-free light source featuring small size, light weight and flexibility in design.
A standard Klaran WR was enhanced and modified to operate with the same power consumption level (6 W) as a comparable mercury lamp system.
Put another way, the Klaran WR system reduced E. Coli in the water to 1/100 of the level of the water disinfected by the mercury lamp system.
