Sorting Column - Case Insensitive but Lower should be first

Question

Hi all,
Lets assume we have am EMployee table :
create table Emp (Empname varchar2(20));
It has following records :
Insert into EMP (EMPNAME) values ('A');
Insert into EMP (EMPNAME) values ('a');
Insert into EMP (EMPNAME) values ('b');
Insert into EMP (EMPNAME) values ('c');
Insert into EMP (EMPNAME) values ('D');
Insert into EMP (EMPNAME) values ('e');
Insert into EMP (EMPNAME) values ('E');
Insert into EMP (EMPNAME) values ('F');
i.e
Empname
A
a
b
c
D
e
E
F
I need output as below : ( Sort by Ascending, case insensitive meaning I don't want all Capital first and then Lower letters. The results should be in alphabetical order it shouldn't matter whether its capital or small. More important is that small letter should come first then the Capital letter). Is this possible?.
Empname
a
A
b
c
D
e
E
F
Select * from emp order by Lower(empname) Asc;
Doesn't do the job, because 'A' comes before 'a'.
