DESCRIPTION:Transparent Conductive Materials (TCM) are key components in m
 any optoelectronic devices such as photovoltaic cells\, LEDs\, Touch scree
 ns\, while they are also used as defrosting coatings. In all these applica
 tions\, the properties off the TCM need to be tuned in order to have the r
 equired combination of resistivity and transparency for every particular a
 pplication.\n\nAt the LMGP we develop a research axis focusing on TCM whic
 h includes electrodes based on Ag nanowire networks\, and both n-type and 
 p-type transparent conductive oxides (TCO). Apart from tuning the transmit
 tance and the transport properties of this electrodes\, we have also devel
 oped a simple method to tune the haze factor (ratio between diffuse and to
 tal transmitted light) of fluorine doped tin oxide (FTO\, an n-type TCO). 
 In my talk I will briefly introduce our research in TCM\, illustrating it 
 with some examples.\n\nIn addition\, I will also introduce a new technique
  we are developing in the lab\, namely\, Spatial Atomic Layer Deposition (
 SALD). SALD is an emerging  variation of conventional ALD in which the pre
 cursors are separated in space rather that in time. As a result\, and whil
 e keeping the key assets offered by ALD\, SALD is orders of magnitude fast
 er and can operate at ambient pressure\, thus being cheaper to scale up.  
 During my talk I will explain the basic of this novel technique and will i
 llustrate its potential to deposit active components for functional device
 s. \n\nFinally\, I will briefly present MOON\, a unique instrument which c
 an be used in-house as a CVD or ALD reactor and also coupled to the synchr
 otron to perform in situ growth studies including diffraction\, fluorescen
 ce\, substrate curvature\, absorption and Raman spectrospcopies.
