Dependence of the NS conductance on the valley polarization of edge states in graphene

The edge states in finite quantum Hall graphene have previously been shown to be valley polarised for zigzag and armchair edges. Assuming that the valley isospin is also conserved at a smooth normal-superconducting (NS) interface, theoretical research has previously predicted that plateaus in the longitudinal conductance are expected to occur in...

Ad Hoc Conditions: Adhocism as a modus operandi for architectural design

The historic city centre of the Lithuanian capital of Vilnius is formed by an urban fabric consisting out of courtyards creating introvert voids within the traditional urban solid. These courtyards contrast the traditional and formal public spaces of the city by the way they operate on the levels of public-private accessibility, spatial...

Light-Emitting Diode Junction-Temperature Sensing using Various Voltage/Current Measurement Techniques

Given the temperature dependence of various aspects of light-emitting diode (LED) performance, LED temperature sensing is becoming increasingly important in solid-state lighting applications. This thesis presents an electrical technique for junction-temperature sensing based on the measurement of the forward voltage and current of an LED at two...
