To answer my own question (An email from my UoS lecturer): "Your answers are all correct except 7.b, where P atoms replaces group VI atoms and semi2 will be p-type." I guess this means that I should just take the higher numbered group type as my basis of comparison to the dopant's group, for...

My favourite microcontroller chipset is ESP8266 and/or ESP32 (Fancier) - Arduino programmable, but cheaper, with builtin WiFi connectivity (ESP32 also has BT). Is there anything in particular you feel would improve your life? Or be helpful to you in some way?

IMO - Invest in a cheap WiFi/Bluetooth enabled dev-board such as the ESP8266 (Inbuilt wifi stack, arduino programmable, strong OS community support), ESP32 (Fancier version of 8266 - Has Bluetooth stack) - A good jumping off point for IoT applications - Make a hall effect smart excercise bike -...

Hi all - This is pulled from a past paper - Homework Statement I'm only going to state the components that I find challenging of this problem - The rest will be attached in my solution set. Essentially - given an intrinsic semiconductor comprised of group II-VI elements. Upon doping with group...

Ivans approach makes plenty of sense - I tried to cut corners and got my comeuppance :D Thank you for your rigorous breakdown - I believe I have it now.

Hi Kuruman, Thank you for answering Ivan's question! I'm actually working on the same past paper (Well, a previous one, with identical parameters) and we've produced quite different results that I'd like to verify. My answer for ## \vec p \cdot \vec r ## was 0, given the two vectors are...
