Acknowledgements
Firstly I would like to express my thanks to my supervisor Dr. James Lloyd-Hughes,
for all the support and guidance he has given me during my Ph.D., and for giving me
the opportunity to undertake this research project. It has been a pleasure to work in
his group for the past four years. I would similarly like to thank all the members of the
THz group at Warwick and those associated with the Warwick Centre for Ultrafast
Spectroscopy, past and present, for making it such a nice environment to work in. I
would particularly like to thank Dr. Michele Failla and Dr. Michael Staniforth for all
the help and advice they have offered me.
I would also like to express my thanks to those who have collaborated with me
on parts of the work presented in this thesis. To Dr. Dharmalingam Prabhakaran
from the University of Oxford for growing the samples of CuO and Cu 0.95 Zn 0.05 O
studied throughout this thesis; to Dr. Mark Ashwin from the University of Warwick
for growing the InSb sample studied in Chap. 5; and to the group of Prof. Albert
Nasibulin from Skoltech and Maria Burdanova from the University of Warwick for
growth and preparation of the single-walled carbon nanotube films studied in Chap. 5.
The work performed in Chap. 4 would not have been possible without the clean room
training and guidance from Dr. Mark Crouch and Dr. Michele Failla. I would also like
to express thanks in this regard to Alan Brunier, in addition to all the coffee breaks
and fun chats. I am also grateful to Dr. Arturo Hernandez Serrano for performing the
simulations of the device emission presented in Chap. 4.
I would like to express my heartfelt thanks to all of the friends I have made during
my time at Warwick, and to all the friends I knew from before. To all my bandmates, it
was a pleasure to share the stage with you. Thanks to Charlie Price and Connor White
for their friendship and support. And to Rebecca Swinney, thank you for everything
you do, I love you.
Finally, I would like to thank my family, especially my mum and dad, for their
unwavering support, encouragement and love. I couldn’t have done this without you,
so this thesis is dedicated to you.
