Biography

The CMOS technology is famously approaching its scaling limit: within the next decade or so, nano-scale FET transistors will reach the sub 5-nm feature size, at which point any further reduction of their sizes will likely become impractical and even impossible due to the thermal fluctuation noise. There are beyond-CMOS and non-charge based alternatives, some of which may be scaled below the 5-nm size and possibly down to atomic sizes. In any case, at this point the foreseeable human scientific and technological capabilities will reach the ultimate scaling limit for the elementary logic and memory device size.


In my research I am trying to answer the following questions:

  • What are the corresponding limits of computation?
  • How much computing can we actually perform and how much information we can actually store with 1 kg of non-exotic matter (i.e. far, far below Bekenstein bound)?
  • Which device-architecture paradigms can allow us to continue increasing FLOPS/kg ratio after the CMOS scaling limit is reached?
  • Can this increase still follow the exponential ("new Moore’s law") trend?

If you like to discuss these and other (e.g. digital physics) fascinating subjects or have an idea about a potential CMOS replacement ­and would like to test it via computer simulation – please give me a call or send me an email.
