Wet chemical synthesis methods can produce semiconductors that consist of 100s to 10,000s of atoms – known as colloidal quantum dots. However, unlike the bulk semiconductors that we are familiar with in electronic devices, they are difficult to controllably dope with impurities. Furthermore, the nature of the size of the crystal impurities (e.g. single point or clusters) and the position (e.g. centre or near the surface) will have an impact on the properties of these crystals. We must understand the quantum effects in these crystals to advance their applications in electronic and optoelectronic devices. To produce electronic devices we will be forming assemblies of these quantum dots to form ‘super-crystals’. Super-crystals are analogous to atoms in a crystal, were the overlapping electron (hole) wave-functions form band-like structure. With close packing the carrier mobilties of >10 cm2V-1s-1 can be obtained. I propose to study novel construction methods for the doped quantum dot super-crystals and study their properties. By understanding the properties of the individual quantum dots and then subsequently how they behave as super-crystals, our vision is to develop methods that would enable low cost construction of flexible quantum dot electronic devices that could be used for field effect transistors (FETs), FET-biosensors, photovoltaics, and thermoelectrics.

<p>Formal applications for research degree study should be made online through the <a href="https://www.leeds.ac.uk/info/130206/applying/91/applying_for_research_degrees">University’s website</a>. Please state clearly in the research information section that the research degree you wish to be considered for is ‘Quantum dot superstructures’ as well as <a href="https://physicalsciences.leeds.ac.uk/staff/104/dr-kevin-critchley">Dr Kevin Critchley</a> as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University's minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>
Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.
The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
