Title:
Quantum Computing: Challenges and Opportunities
Abstract
Quantum computing is an entirely new paradigm of computation that
promises to solve some of the most difficult problems that are
currently intractable on classical supercomputers. Governments and
large technology firms around the world have announced billions of
dollars for the field. In this talk, I will give an overview on the
recent development of quantum computers and quantum computing, and then
talk about challenges and opportunities of this exciting technology.
Finally, I will discuss the broader effort in quantum computing at the
National Taiwan University (NTU).

Title:
Photoelectric effect with
more than one electron
Abstract
Beginning with the development of quantum mechanics, photoelectric
effect has become a useful method to characterize the electronic
structure of materials. In the traditional picture of the photoelectric
effect, an incident photon is absorbed by one single electron. As a
consequence, the electronic states in materials can be retrieved by the
kinetic energy and the emission angle of the photoelectron. This
relation underlies the angle-resolved photoelectron spectroscopy, which
has been routinely applied to characterize the band structure of solids
nowadays. In strong contrast, there exist pathways in solids where more
than one photoelectron can be generated by one individual photon. In
the simplest case, a pair of electrons can be emitted from a solid
surface after the absorption of one single photon. This double
photoemission (DPE) process on solids was discovered and outlined
theoretically several decades ago. In this talk, DPE spectroscopy on
solids will be introduced. The experimental setup of DPE consists of a
pair of time-of-flight photoelectron spectrometers and a home-built
high-order harmonic light source using a femtosecond laser. The DPE
spectra on Ag(001) and Cu(111) surfaces reveal the band-dependent
emission of electron pairs and will be discussed in terms of the
characteristic electron-electron interaction in these materials. These
spectra will be compared with DPE on the strongly correlated NiO films,
where indications of multiple excitations of the d electrons are found

Title:
Moore's
law continues
Abstract
電子學課本教我們0.35微米的技術節點，所用的電晶體gate
length就是0.35um。但現在台積電量產的主力產品是7nm，很多同學都會以為電晶體的gate length還是7nm。
現在我在台大我們已經開始做2nm的技術節點，很多同學都很擔心gate
length為2nm的電晶體，理論上是非常困難的，因此就覺得超越2nm的技術節點是不可能。
到底什麼是Moore's law的定義？主要是指單位面積電晶體的個數，每一代要增加為兩倍，並沒有指定電晶體的gate
length就是技術節點的大小。
在台大我們利用(1) 3D電晶體，(2) stacked transistors，(3) GeSi/GeSn epitaxy，(4) 3D
cell有希望可以將技術節點超越1nm。希望能夠跟各位同學分享台大的榮耀。
