Atomic layer deposition of dielectrics, nitrides and metals with low damage. Our unique cluster capability provides the ability to cover surfaces directly without exposure to air. For instance these could be etched interfaces or freshly grown 2D materials such as MoS2 or graphene covered by ALD dielectrics or capping layers which can be a big advantage for a wide range of devices.

Chemical Vapour Deposition & ALD of atomically thin structures: 1D & 2D materials.
Unique devices can be constructed by covering nanowires with ALD films or etching 1D and 2D materials to tune their properties.

CVD growth of hBN
Atomic layer etching of Silicon, GaN & 2D materials. As these materials perform essential functions in a wide range of devices, our ability to etch these with extreme control and low damage can be an enabling technology. Furthermore combining ALE with deposition and growth will provide unique advantages in your device making.
